-// COMPILE-TIME OPTIONS FOR DEAR IMGUI
-// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
-// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.
-//-----------------------------------------------------------------------------
-// A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/rebased branch with your modifications to it)
-// B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template.
-//-----------------------------------------------------------------------------
-// You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp
-// files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.
-// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.
-// Call IMGUI_CHECKVERSION() from your .cpp files to verify that the data structures your files are using are matching the ones imgui.cpp is using.
-//-----------------------------------------------------------------------------

-
-//---- Debug Tools: Have the Item Picker break in the ItemAdd() function instead of ItemHoverable(),

- MISSION STATEMENT
- =================
-
- - Easy to use to create code-driven and data-driven tools.
- - Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools.
- - Easy to hack and improve.
- - Minimize screen real-estate usage.
- - Minimize setup and maintenance.
- - Minimize state storage on user side.
- - Portable, minimize dependencies, run on target (consoles, phones, etc.).
- - Efficient runtime and memory consumption (NB- we do allocate when "growing" content e.g. creating a window,.
-   opening a tree node for the first time, etc. but a typical frame should not allocate anything).
-
- Designed for developers and content-creators, not the typical end-user! Some of the weaknesses includes:
- - Doesn't look fancy, doesn't animate.
- - Limited layout features, intricate layouts are typically crafted in code.
-
-
- END-USER GUIDE
- ==============
-
- - Double-click on title bar to collapse window.
- - Click upper right corner to close a window, available when 'bool* p_open' is passed to ImGui::Begin().
- - Click and drag on lower right corner to resize window (double-click to auto fit window to its contents).
- - Click and drag on any empty space to move window.
- - TAB/SHIFT+TAB to cycle through keyboard editable fields.
- - CTRL+Click on a slider or drag box to input value as text.
- - Use mouse wheel to scroll.
- - Text editor:
-   - Hold SHIFT or use mouse to select text.
-   - CTRL+Left/Right to word jump.
-   - CTRL+Shift+Left/Right to select words.
-   - CTRL+A our Double-Click to select all.
-   - CTRL+X,CTRL+C,CTRL+V to use OS clipboard/
-   - CTRL+Z,CTRL+Y to undo/redo.
-   - ESCAPE to revert text to its original value.
-   - You can apply arithmetic operators +,*,/ on numerical values. Use +- to subtract (because - would set a negative value!)
-   - Controls are automatically adjusted for OSX to match standard OSX text editing operations.
- - General Keyboard controls: enable with ImGuiConfigFlags_NavEnableKeyboard.
- - General Gamepad controls: enable with ImGuiConfigFlags_NavEnableGamepad. See suggested mappings in imgui.h ImGuiNavInput_ + download PNG/PSD at http://goo.gl/9LgVZW

- PROGRAMMER GUIDE
- ================
-
- READ FIRST
- ----------
- - Remember to read the FAQ (https://www.dearimgui.org/faq)
- - Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction
-   or destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, less bugs.
- - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features.
- - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build.
- - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori).
-   You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in the FAQ.
- - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances.
-   For every application frame your UI code will be called only once. This is in contrast to e.g. Unity's own implementation of an IMGUI,
-   where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches.
- - Our origin are on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right.
- - This codebase is also optimized to yield decent performances with typical "Debug" builds settings.
- - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected).
-   If you get an assert, read the messages and comments around the assert.
- - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace.
- - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types.
-   See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that.
-   However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase.
- - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!).
-
-
- HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI
- ----------------------------------------------
- - Overwrite all the sources files except for imconfig.h (if you have made modification to your copy of imconfig.h)
- - Or maintain your own branch where you have imconfig.h modified.
- - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes.
-   If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed
-   from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will
-   likely be a comment about it. Please report any issue to the GitHub page!
- - Try to keep your copy of dear imgui reasonably up to date.
-
-
- GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE
- ---------------------------------------------------------------
- - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library.
- - In the majority of cases you should be able to use unmodified back-ends files available in the examples/ folder.
- - Add the Dear ImGui source files + selected back-end source files to your projects or using your preferred build system.
-   It is recommended you build and statically link the .cpp files as part of your project and NOT as shared library (DLL).
- - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types.
- - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.
- - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide.
-   Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render"
-   phases of your own application. All rendering information are stored into command-lists that you will retrieve after calling ImGui::Render().
- - Refer to the bindings and demo applications in the examples/ folder for instruction on how to setup your code.
- - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder.
-
-
- HOW A SIMPLE APPLICATION MAY LOOK LIKE
- --------------------------------------
- EXHIBIT 1: USING THE EXAMPLE BINDINGS (= imgui_impl_XXX.cpp files from the examples/ folder).
- The sub-folders in examples/ contains examples applications following this structure.
-
-     // Application init: create a dear imgui context, setup some options, load fonts
-     ImGui::CreateContext();
-     ImGuiIO& io = ImGui::GetIO();
-     // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
-     // TODO: Fill optional fields of the io structure later.
-     // TODO: Load TTF/OTF fonts if you don't want to use the default font.
-
-     // Initialize helper Platform and Renderer bindings (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp)
-     ImGui_ImplWin32_Init(hwnd);
-     ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext);
-
-     // Application main loop
-     while (true)
-     {
-         // Feed inputs to dear imgui, start new frame
-         ImGui_ImplDX11_NewFrame();
-         ImGui_ImplWin32_NewFrame();
-         ImGui::NewFrame();
-
-         // Any application code here
-         ImGui::Text("Hello, world!");
-
-         // Render dear imgui into screen
-         ImGui::Render();
-         ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData());
-         g_pSwapChain->Present(1, 0);
-     }
-
-     // Shutdown
-     ImGui_ImplDX11_Shutdown();
-     ImGui_ImplWin32_Shutdown();
-     ImGui::DestroyContext();
-
- EXHIBIT 2: IMPLEMENTING CUSTOM BINDING / CUSTOM ENGINE
-
-     // Application init: create a dear imgui context, setup some options, load fonts
-     ImGui::CreateContext();
-     ImGuiIO& io = ImGui::GetIO();
-     // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
-     // TODO: Fill optional fields of the io structure later.
-     // TODO: Load TTF/OTF fonts if you don't want to use the default font.
-
-     // Build and load the texture atlas into a texture
-     // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer)
-     int width, height;
-     unsigned char* pixels = NULL;
-     io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);
-
-     // At this point you've got the texture data and you need to upload that your your graphic system:
-     // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'.
-     // This will be passed back to your via the renderer. Basically ImTextureID == void*. Read FAQ for details about ImTextureID.
-     MyTexture* texture = MyEngine::CreateTextureFromMemoryPixels(pixels, width, height, TEXTURE_TYPE_RGBA32)
-     io.Fonts->TexID = (void*)texture;
-
-     // Application main loop
-     while (true)
-     {
-        // Setup low-level inputs, e.g. on Win32: calling GetKeyboardState(), or write to those fields from your Windows message handlers, etc.
-        // (In the examples/ app this is usually done within the ImGui_ImplXXX_NewFrame() function from one of the demo Platform bindings)
-        io.DeltaTime = 1.0f/60.0f;              // set the time elapsed since the previous frame (in seconds)
-        io.DisplaySize.x = 1920.0f;             // set the current display width
-        io.DisplaySize.y = 1280.0f;             // set the current display height here
-        io.MousePos = my_mouse_pos;             // set the mouse position
-        io.MouseDown[0] = my_mouse_buttons[0];  // set the mouse button states
-        io.MouseDown[1] = my_mouse_buttons[1];
-
-        // Call NewFrame(), after this point you can use ImGui::* functions anytime
-        // (So you want to try calling NewFrame() as early as you can in your mainloop to be able to use Dear ImGui everywhere)
-        ImGui::NewFrame();
-
-        // Most of your application code here
-        ImGui::Text("Hello, world!");
-        MyGameUpdate(); // may use any Dear ImGui functions, e.g. ImGui::Begin("My window"); ImGui::Text("Hello, world!"); ImGui::End();
-        MyGameRender(); // may use any Dear ImGui functions as well!
-
-        // Render dear imgui, swap buffers
-        // (You want to try calling EndFrame/Render as late as you can, to be able to use Dear ImGui in your own game rendering code)
-        ImGui::EndFrame();
-        ImGui::Render();
-        ImDrawData* draw_data = ImGui::GetDrawData();
-        MyImGuiRenderFunction(draw_data);
-        SwapBuffers();
-     }
-
-     // Shutdown
-     ImGui::DestroyContext();
-
- To decide whether to dispatch mouse/keyboard inputs to Dear ImGui to the rest your application,
- you should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags!
- Please read the FAQ and example applications for details about this!
-
-
- HOW A SIMPLE RENDERING FUNCTION MAY LOOK LIKE
- ---------------------------------------------
- The bindings in impl_impl_XXX.cpp files contains many working implementations of a rendering function.
-
-    void void MyImGuiRenderFunction(ImDrawData* draw_data)
-    {
-       // TODO: Setup render state: alpha-blending enabled, no face culling, no depth testing, scissor enabled

- USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS
- ------------------------------------------
- - The gamepad/keyboard navigation is fairly functional and keeps being improved.
- - Gamepad support is particularly useful to use Dear ImGui on a console system (e.g. PS4, Switch, XB1) without a mouse!
- - You can ask questions and report issues at https://github.com/ocornut/imgui/issues/787
- - The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.
- - Keyboard:
-    - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.
-      NewFrame() will automatically fill io.NavInputs[] based on your io.KeysDown[] + io.KeyMap[] arrays.
-    - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag
-      will be set. For more advanced uses, you may want to read from:
-       - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
-       - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used).
-       - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions.
-      Please reach out if you think the game vs navigation input sharing could be improved.
- - Gamepad:
-    - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.
-    - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame().
-      Note that io.NavInputs[] is cleared by EndFrame().
-    - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. For each entry of io.NavInputs[], set the following values:
-         0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks.
-    - We uses a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone.
-      Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
-    - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://goo.gl/9LgVZW.
-    - If you need to share inputs between your game and the imgui parts, the easiest approach is to go all-or-nothing, with a buttons combo
-      to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.
- - Mouse:
-    - PS4 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback.
-    - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard.
-    - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag.
-      Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements.
-      When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved.
-      When that happens your back-end NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the binding in examples/ do that.
-      (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse as moving back and forth!)
-      (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want
-       to set a boolean to ignore your other external mouse positions until the external source is moved again.)

- API BREAKING CHANGES
- ====================
-
- Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix.
- Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code.
- When you are not sure about a old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files.
- You can read releases logs https://github.com/ocornut/imgui/releases for more details.
-
- - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently).
- - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton.
- - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory.
- - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result.
- - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. It was also getting in the way of better font scaling, so let's get rid of it now!
- - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar().
-                       replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags).
-                       worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions:
-                       - if you omitted the 'power' parameter (likely!), you are not affected.
-                       - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct.
-                       - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f.
-                       see https://github.com/ocornut/imgui/issues/3361 for all details.
-                       kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version were removed directly as they were most unlikely ever used.
-                       for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`.
-                     - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime.
- - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems.
- - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79]
- - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017.
- - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular().
- - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more.
- - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead.
- - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value.
- - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017):
-                       - ShowTestWindow()                    -> use ShowDemoWindow()
-                       - IsRootWindowFocused()               -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow)
-                       - IsRootWindowOrAnyChildFocused()     -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)
-                       - SetNextWindowContentWidth(w)        -> use SetNextWindowContentSize(ImVec2(w, 0.0f)
-                       - GetItemsLineHeightWithSpacing()     -> use GetFrameHeightWithSpacing()
-                       - ImGuiCol_ChildWindowBg              -> use ImGuiCol_ChildBg
-                       - ImGuiStyleVar_ChildWindowRounding   -> use ImGuiStyleVar_ChildRounding
-                       - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap
-                       - IMGUI_DISABLE_TEST_WINDOWS          -> use IMGUI_DISABLE_DEMO_WINDOWS
- - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was the vaguely documented and rarely if ever used). Instead we added an explicit PrimUnreserve() API.
- - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it).
- - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert.
- - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency.
- - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency.
- - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017):
-                       - Begin() [old 5 args version]        -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed
-                       - IsRootWindowOrAnyChildHovered()     -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)
-                       - AlignFirstTextHeightToWidgets()     -> use AlignTextToFramePadding()
-                       - SetNextWindowPosCenter()            -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f)
-                       - ImFont::Glyph                       -> use ImFontGlyph
- - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function.
-                       if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix.
-                       The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay).
-                       If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you.
- - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete).
- - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete).
- - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71.
- - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have
-                       overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering.
-                       This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows.
-                       Please reach out if you are affected.
- - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete).
- - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c).
- - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now.
- - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete).
- - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete).
- - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete).
- - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrary small value!
- - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already).
- - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead!
- - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete).
- - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects.
- - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags.
- - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files.
- - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete).
- - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h.
-                       If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths.
- - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427)
- - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp.
-                       NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED.
-                       Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions.
- - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent).
- - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete).
- - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly).
- - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature.
- - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency.
- - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.
- - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).
- - 2018/06/08 (1.62) - examples: the imgui_impl_xxx files have been split to separate platform (Win32, Glfw, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan,  etc.).
-                       old bindings will still work as is, however prefer using the separated bindings as they will be updated to support multi-viewports.
-                       when adopting new bindings follow the main.cpp code of your preferred examples/ folder to know which functions to call.
-                       in particular, note that old bindings called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function.
- - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set.
- - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details.
- - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more.
-                       If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format.
-                       To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code.
-                       If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them.
- - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format",
-                       consistent with other functions. Kept redirection functions (will obsolete).
- - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value.
- - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some binding ahead of merging the Nav branch).
- - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now.
- - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically.
- - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
- - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.
- - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display.
- - 2018/02/07 (1.60) - reorganized context handling to be more explicit,
-                       - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
-                       - removed Shutdown() function, as DestroyContext() serve this purpose.
-                       - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance.
-                       - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.
-                       - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts.
- - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths.
- - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
- - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
- - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
- - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side.
- - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).
- - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags
- - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame.
- - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set.
- - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete).
- - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete).
-                     - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete).
- - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete).
- - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete).
- - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
- - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up.
-                       Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions.
- - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency.
- - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg.
- - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.
- - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows);
- - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency.
- - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it.
- - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details.
-                       removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting.
-                         IsItemHoveredRect()        --> IsItemHovered(ImGuiHoveredFlags_RectOnly)
-                         IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow)
-                         IsMouseHoveringWindow()    --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior]
- - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead!
- - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete).
- - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete).
- - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete).
- - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your binding if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)".
- - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)!
-                     - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete).
-                     - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete).
- - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency.
- - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.
- - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type.
- - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely.
- - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete).
- - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete).
- - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().
- - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.
-                     - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
-                     - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))'
- - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse
- - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.
- - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity.
- - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild().
- - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it.
- - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.
- - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal.
- - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore.
-                       If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.
-                       This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color:
-                       ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); }
-                       If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.
- - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext().
- - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection.
- - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen).
- - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.
- - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337).
- - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337)
- - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete).
- - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert.
- - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.
- - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis.
- - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete.
- - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position.
-                       GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side.
-                       GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out!
- - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize
- - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project.
- - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason
- - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure.
-                       you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text.
- - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
-                       this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
-                     - if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
-                     - the signature of the io.RenderDrawListsFn handler has changed!
-                       old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
-                       new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).
-                         parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount'
-                         ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new.
-                         ImDrawCmd:  'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'.
-                     - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
-                     - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
-                     - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!
- - 2015/07/10 (1.43) - changed SameLine() parameters from int to float.
- - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).
- - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount.
- - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence
- - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely be used. Sorry!
- - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete).
- - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete).
- - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons.
- - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened.
- - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
- - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50.
- - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API
- - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.
- - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.
- - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50.
- - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing
- - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50.
- - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing)
- - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50.
- - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once.
- - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now.
- - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior
- - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing()
- - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused)
- - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.
- - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader.
- - 2015/01/11 (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels.
-                       - old:  const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); [..Upload texture to GPU..];
-                       - new:  unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); [..Upload texture to GPU..]; io.Fonts->TexId = YourTexIdentifier;
-                       you now have more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. It is now recommended that you sample the font texture with bilinear interpolation.
- - 2015/01/11 (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to set io.Fonts->TexID.
- - 2015/01/11 (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix)
- - 2015/01/11 (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets
- - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver)
- - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph)
- - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility
- - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered()
- - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly)
- - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity)
- - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale()
- - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn
- - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically)
- - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite
- - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes

-
- Q&A: Basics
- ===========
-
- Q: Where is the documentation?
- A: This library is poorly documented at the moment and expects of the user to be acquainted with C/C++.
-    - Run the examples/ and explore them.
-    - See demo code in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function.
-    - The demo covers most features of Dear ImGui, so you can read the code and see its output.
-    - See documentation and comments at the top of imgui.cpp + effectively imgui.h.
-    - Dozens of standalone example applications using e.g. OpenGL/DirectX are provided in the
-      examples/ folder to explain how to integrate Dear ImGui with your own engine/application.
-    - The Wiki (https://github.com/ocornut/imgui/wiki) has many resources and links.
-    - The Glossary (https://github.com/ocornut/imgui/wiki/Glossary) page also may be useful.
-    - Your programming IDE is your friend, find the type or function declaration to find comments
-      associated to it.
-
- Q: What is this library called?
- Q: Which version should I get?
- >> This library is called "Dear ImGui", please don't call it "ImGui" :)
- >> See https://www.dearimgui.org/faq for details.
-
- Q&A: Integration
- ================
-
- Q: How to get started?
- A: Read 'PROGRAMMER GUIDE' above. Read examples/README.txt.
-
- Q: How can I tell whether to dispatch mouse/keyboard to Dear ImGui or to my application?
- A: You should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags!
- >> See https://www.dearimgui.org/faq for fully detailed answer. You really want to read this.
-
- Q. How can I enable keyboard controls?
- Q: How can I use this without a mouse, without a keyboard or without a screen? (gamepad, input share, remote display)
- Q: I integrated Dear ImGui in my engine and little squares are showing instead of text..
- Q: I integrated Dear ImGui in my engine and some elements are clipping or disappearing when I move windows around..
- Q: I integrated Dear ImGui in my engine and some elements are displaying outside their expected windows boundaries..
- >> See https://www.dearimgui.org/faq
-
- Q&A: Usage
- ----------
-
- Q: Why is my widget not reacting when I click on it?
- Q: How can I have widgets with an empty label?
- Q: How can I have multiple widgets with the same label?
- Q: How can I display an image? What is ImTextureID, how does it works?
- Q: How can I use my own math types instead of ImVec2/ImVec4?
- Q: How can I interact with standard C++ types (such as std::string and std::vector)?
- Q: How can I display custom shapes? (using low-level ImDrawList API)
- >> See https://www.dearimgui.org/faq
-
- Q&A: Fonts, Text
- ================
-
- Q: How should I handle DPI in my application?
- Q: How can I load a different font than the default?
- Q: How can I easily use icons in my application?
- Q: How can I load multiple fonts?
- Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic?
- >> See https://www.dearimgui.org/faq and https://github.com/ocornut/imgui/edit/master/docs/FONTS.md
-
- Q&A: Concerns
- =============
-
- Q: Who uses Dear ImGui?
- Q: Can you create elaborate/serious tools with Dear ImGui?
- Q: Can you reskin the look of Dear ImGui?
- Q: Why using C++ (as opposed to C)?
- >> See https://www.dearimgui.org/faq
-
- Q&A: Community
- ==============
-
- Q: How can I help?
- A: - Businesses: please reach out to "contact AT dearimgui.org" if you work in a place using Dear ImGui!
-      We can discuss ways for your company to fund development via invoiced technical support, maintenance or sponsoring contacts.
-      This is among the most useful thing you can do for Dear ImGui. With increased funding we can hire more people working on this project.
-    - Individuals: you can support continued development via PayPal donations. See README.
-    - If you are experienced with Dear ImGui and C++, look at the github issues, look at the Wiki, read docs/TODO.txt
-      and see how you want to help and can help!
-    - Disclose your usage of Dear ImGui via a dev blog post, a tweet, a screenshot, a mention somewhere etc.
-      You may post screenshot or links in the gallery threads (github.com/ocornut/imgui/issues/3075). Visuals are ideal as they inspire other programmers.
-      But even without visuals, disclosing your use of dear imgui help the library grow credibility, and help other teams and programmers with taking decisions.
-    - If you have issues or if you need to hack into the library, even if you don't expect any support it is useful that you share your issues (on github or privately).

-// [SECTION] CONTEXT AND MEMORY ALLOCATORS
-//-----------------------------------------------------------------------------
-
-// Current context pointer. Implicitly used by all Dear ImGui functions. Always assumed to be != NULL.
-// ImGui::CreateContext() will automatically set this pointer if it is NULL. Change to a different context by calling ImGui::SetCurrentContext().
-// 1) Important: globals are not shared across DLL boundaries! If you use DLLs or any form of hot-reloading: you will need to call
-//    SetCurrentContext() (with the pointer you got from CreateContext) from each unique static/DLL boundary, and after each hot-reloading.
-//    In your debugger, add GImGui to your watch window and notice how its value changes depending on which location you are currently stepping into.
-// 2) Important: Dear ImGui functions are not thread-safe because of this pointer.
-//    If you want thread-safety to allow N threads to access N different contexts, you can:
-//    - Change this variable to use thread local storage so each thread can refer to a different context, in imconfig.h:
-//          struct ImGuiContext;
-//          extern thread_local ImGuiContext* MyImGuiTLS;
-//          #define GImGui MyImGuiTLS
-//      And then define MyImGuiTLS in one of your cpp file. Note that thread_local is a C++11 keyword, earlier C++ uses compiler-specific keyword.
-//    - Future development aim to make this context pointer explicit to all calls. Also read https://github.com/ocornut/imgui/issues/586
-//    - If you need a finite number of contexts, you may compile and use multiple instances of the ImGui code from different namespace.
-#ifndef GImGui
-ImGuiContext*   GImGui = NULL;
-#endif
-
-// Memory Allocator functions. Use SetAllocatorFunctions() to change them.
-// If you use DLL hotreloading you might need to call SetAllocatorFunctions() after reloading code from this file.
-// Otherwise, you probably don't want to modify them mid-program, and if you use global/static e.g. ImVector<> instances you may need to keep them accessible during program destruction.

-// - Important: our implementation does NOT call C++ constructors/destructors, we treat everything as raw data! This is intentional but be extra mindful of that,

-// Helper: Manually clip large list of items.
-// If you are submitting lots of evenly spaced items and you have a random access to the list, you can perform coarse clipping based on visibility to save yourself from processing those items at all.
-// The clipper calculates the range of visible items and advance the cursor to compensate for the non-visible items we have skipped.
-// ImGui already clip items based on their bounds but it needs to measure text size to do so. Coarse clipping before submission makes this cost and your own data fetching/submission cost null.
-// Usage:
-//     ImGuiListClipper clipper(1000);  // we have 1000 elements, evenly spaced.
-//     while (clipper.Step())
-//         for (int i = clipper.DisplayStart; i < clipper.DisplayEnd; i++)
-//             ImGui::Text("line number %d", i);
-// - Step 0: the clipper let you process the first element, regardless of it being visible or not, so we can measure the element height (step skipped if we passed a known height as second arg to constructor).
-// - Step 1: the clipper infer height from first element, calculate the actual range of elements to display, and position the cursor before the first element.
-// - (Step 2: empty step only required if an explicit items_height was passed to constructor or Begin() and user call Step(). Does nothing and switch to Step 3.)
-// - Step 3: the clipper validate that we have reached the expected Y position (corresponding to element DisplayEnd), advance the cursor to the end of the list and then returns 'false' to end the loop.

-//  - Mouse cursor shapes for software cursor rendering (unless setting 'Flags |= ImFontAtlasFlags_NoMouseCursors' in the font atlas).
-// It is the user-code responsibility to setup/build the atlas, then upload the pixel data into a texture accessible by your graphics api.
-//  - Optionally, call any of the AddFont*** functions. If you don't call any, the default font embedded in the code will be loaded for you.
-//  - Call GetTexDataAsAlpha8() or GetTexDataAsRGBA32() to build and retrieve pixels data.
-//  - Upload the pixels data into a texture within your graphics system (see imgui_impl_xxxx.cpp examples)
-//  - Call SetTexID(my_tex_id); and pass the pointer/identifier to your texture in a format natural to your graphics API.
-//    This value will be passed back to you during rendering to identify the texture. Read FAQ entry about ImTextureID for more details.
-// Common pitfalls:
-// - If you pass a 'glyph_ranges' array to AddFont*** functions, you need to make sure that your array persist up until the
-//   atlas is build (when calling GetTexData*** or Build()). We only copy the pointer, not the data.
-// - Important: By default, AddFontFromMemoryTTF() takes ownership of the data. Even though we are not writing to it, we will free the pointer on destruction.
-//   You can set font_cfg->FontDataOwnedByAtlas=false to keep ownership of your data and it won't be freed,
-// - Even though many functions are suffixed with "TTF", OTF data is supported just as well.
-// - This is an old API and it is currently awkward for those and and various other reasons! We will address them in the future!

-// dear imgui, v1.79 WIP
-// (demo code)
-
-// Help:
-// - Read FAQ at http://dearimgui.org/faq
-// - Newcomers, read 'Programmer guide' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
-// - Call and read ImGui::ShowDemoWindow() in imgui_demo.cpp. All applications in examples/ are doing that.
-// Read imgui.cpp for more details, documentation and comments.
-// Get latest version at https://github.com/ocornut/imgui
-
-// Message to the person tempted to delete this file when integrating Dear ImGui into their code base:
-// Do NOT remove this file from your project! Think again! It is the most useful reference code that you and other
-// coders will want to refer to and call. Have the ImGui::ShowDemoWindow() function wired in an always-available
-// debug menu of your game/app! Removing this file from your project is hindering access to documentation for everyone
-// in your team, likely leading you to poorer usage of the library.
-// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow().
-// If you want to link core Dear ImGui in your shipped builds but want a thorough guarantee that the demo will not be
-// linked, you can setup your imconfig.h with #define IMGUI_DISABLE_DEMO_WINDOWS and those functions will be empty.
-// In other situation, whenever you have Dear ImGui available you probably want this to be available for reference.
-// Thank you,
-// -Your beloved friend, imgui_demo.cpp (which you won't delete)
-
-// Message to beginner C/C++ programmers about the meaning of the 'static' keyword:
-// In this demo code, we frequently we use 'static' variables inside functions. A static variable persist across calls,
-// so it is essentially like a global variable but declared inside the scope of the function. We do this as a way to
-// gather code and data in the same place, to make the demo source code faster to read, faster to write, and smaller
-// in size. It also happens to be a convenient way of storing simple UI related information as long as your function
-// doesn't need to be reentrant or used in multiple threads. This might be a pattern you will want to use in your code,
-// but most of the real data you would be editing is likely going to be stored outside your functions.
-
-// The Demo code in this file is designed to be easy to copy-and-paste in into your application!
-// Because of this:
-// - We never omit the ImGui:: prefix when calling functions, even though most code here is in the same namespace.
-// - We try to declare static variables in the local scope, as close as possible to the code using them.
-// - We never use any of the helpers/facilities used internally by Dear ImGui, unless available in the public API.
-// - We never use maths operators on ImVec2/ImVec4. For our other sources files we use them, and they are provided
-//   by imgui_internal.h using the IMGUI_DEFINE_MATH_OPERATORS define. For your own sources file they are optional
-//   and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h.
-//   Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp.

-// Because we handle so many cases (keyboard/gamepad navigation, drag and drop) and many specific behavior (via ImGuiButtonFlags_),

-// By far the most common path is interacting with the Mouse using the default ImGuiButtonFlags_PressedOnClickRelease button behavior.

-// [DEAR IMGUI]
-// This is a slightly modified version of stb_rect_pack.h 1.00.
-// Those changes would need to be pushed into nothings/stb:
-// - Added STBRP__CDECL
-// Grep for [DEAR IMGUI] to find the changes.
-
-// stb_rect_pack.h - v1.00 - public domain - rectangle packing
-// Sean Barrett 2014
-//
-// Useful for e.g. packing rectangular textures into an atlas.
-// Does not do rotation.
-//
-// Not necessarily the awesomest packing method, but better than
-// the totally naive one in stb_truetype (which is primarily what
-// this is meant to replace).
-//
-// Has only had a few tests run, may have issues.
-//
-// More docs to come.
-//
-// No memory allocations; uses qsort() and assert() from stdlib.
-// Can override those by defining STBRP_SORT and STBRP_ASSERT.
-//
-// This library currently uses the Skyline Bottom-Left algorithm.
-//
-// Please note: better rectangle packers are welcome! Please
-// implement them to the same API, but with a different init
-// function.

-// [DEAR IMGUI]
-// This is a slightly modified version of stb_textedit.h 1.13. 
-// Those changes would need to be pushed into nothings/stb:
-// - Fix in stb_textedit_discard_redo (see https://github.com/nothings/stb/issues/321)
-// Grep for [DEAR IMGUI] to find the changes.
-
-// stb_textedit.h - v1.13  - public domain - Sean Barrett
-// Development of this library was sponsored by RAD Game Tools
-//
-// This C header file implements the guts of a multi-line text-editing
-// widget; you implement display, word-wrapping, and low-level string
-// insertion/deletion, and stb_textedit will map user inputs into
-// insertions & deletions, plus updates to the cursor position,
-// selection state, and undo state.
-//
-// It is intended for use in games and other systems that need to build
-// their own custom widgets and which do not have heavy text-editing
-// requirements (this library is not recommended for use for editing large
-// texts, as its performance does not scale and it has limited undo).
-//
-// Non-trivial behaviors are modelled after Windows text controls.
-// 
-//

-//
-// USAGE
-//
-// This file behaves differently depending on what symbols you define
-// before including it.
-//
-//
-// Header-file mode:
-//
-//   If you do not define STB_TEXTEDIT_IMPLEMENTATION before including this,
-//   it will operate in "header file" mode. In this mode, it declares a
-//   single public symbol, STB_TexteditState, which encapsulates the current
-//   state of a text widget (except for the string, which you will store
-//   separately).
-//
-//   To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a
-//   primitive type that defines a single character (e.g. char, wchar_t, etc).
-//
-//   To save space or increase undo-ability, you can optionally define the
-//   following things that are used by the undo system:
-//
-//      STB_TEXTEDIT_POSITIONTYPE         small int type encoding a valid cursor position
-//      STB_TEXTEDIT_UNDOSTATECOUNT       the number of undo states to allow
-//      STB_TEXTEDIT_UNDOCHARCOUNT        the number of characters to store in the undo buffer
-//
-//   If you don't define these, they are set to permissive types and
-//   moderate sizes. The undo system does no memory allocations, so
-//   it grows STB_TexteditState by the worst-case storage which is (in bytes):
-//
-//        [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATE_COUNT
-//      +          sizeof(STB_TEXTEDIT_CHARTYPE)      * STB_TEXTEDIT_UNDOCHAR_COUNT
-//
-//
-// Implementation mode:
-//
-//   If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it
-//   will compile the implementation of the text edit widget, depending
-//   on a large number of symbols which must be defined before the include.
-//
-//   The implementation is defined only as static functions. You will then
-//   need to provide your own APIs in the same file which will access the
-//   static functions.
-//
-//   The basic concept is that you provide a "string" object which
-//   behaves like an array of characters. stb_textedit uses indices to
-//   refer to positions in the string, implicitly representing positions
-//   in the displayed textedit. This is true for both plain text and
-//   rich text; even with rich text stb_truetype interacts with your
-//   code as if there was an array of all the displayed characters.
-//
-// Symbols that must be the same in header-file and implementation mode:
-//
-//     STB_TEXTEDIT_CHARTYPE             the character type
-//     STB_TEXTEDIT_POSITIONTYPE         small type that is a valid cursor position
-//     STB_TEXTEDIT_UNDOSTATECOUNT       the number of undo states to allow
-//     STB_TEXTEDIT_UNDOCHARCOUNT        the number of characters to store in the undo buffer
-//
-// Symbols you must define for implementation mode:
-//
-//    STB_TEXTEDIT_STRING               the type of object representing a string being edited,
-//                                      typically this is a wrapper object with other data you need
-//
-//    STB_TEXTEDIT_STRINGLEN(obj)       the length of the string (ideally O(1))
-//    STB_TEXTEDIT_LAYOUTROW(&r,obj,n)  returns the results of laying out a line of characters
-//                                        starting from character #n (see discussion below)
-//    STB_TEXTEDIT_GETWIDTH(obj,n,i)    returns the pixel delta from the xpos of the i'th character
-//                                        to the xpos of the i+1'th char for a line of characters
-//                                        starting at character #n (i.e. accounts for kerning
-//                                        with previous char)
-//    STB_TEXTEDIT_KEYTOTEXT(k)         maps a keyboard input to an insertable character
-//                                        (return type is int, -1 means not valid to insert)
-//    STB_TEXTEDIT_GETCHAR(obj,i)       returns the i'th character of obj, 0-based
-//    STB_TEXTEDIT_NEWLINE              the character returned by _GETCHAR() we recognize
-//                                        as manually wordwrapping for end-of-line positioning
-//
-//    STB_TEXTEDIT_DELETECHARS(obj,i,n)      delete n characters starting at i
-//    STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n)   insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*)
-//
-//    STB_TEXTEDIT_K_SHIFT       a power of two that is or'd in to a keyboard input to represent the shift key
-//
-//    STB_TEXTEDIT_K_LEFT        keyboard input to move cursor left
-//    STB_TEXTEDIT_K_RIGHT       keyboard input to move cursor right
-//    STB_TEXTEDIT_K_UP          keyboard input to move cursor up
-//    STB_TEXTEDIT_K_DOWN        keyboard input to move cursor down
-//    STB_TEXTEDIT_K_PGUP        keyboard input to move cursor up a page
-//    STB_TEXTEDIT_K_PGDOWN      keyboard input to move cursor down a page
-//    STB_TEXTEDIT_K_LINESTART   keyboard input to move cursor to start of line  // e.g. HOME
-//    STB_TEXTEDIT_K_LINEEND     keyboard input to move cursor to end of line    // e.g. END
-//    STB_TEXTEDIT_K_TEXTSTART   keyboard input to move cursor to start of text  // e.g. ctrl-HOME
-//    STB_TEXTEDIT_K_TEXTEND     keyboard input to move cursor to end of text    // e.g. ctrl-END
-//    STB_TEXTEDIT_K_DELETE      keyboard input to delete selection or character under cursor
-//    STB_TEXTEDIT_K_BACKSPACE   keyboard input to delete selection or character left of cursor
-//    STB_TEXTEDIT_K_UNDO        keyboard input to perform undo
-//    STB_TEXTEDIT_K_REDO        keyboard input to perform redo
-//
-// Optional:
-//    STB_TEXTEDIT_K_INSERT              keyboard input to toggle insert mode
-//    STB_TEXTEDIT_IS_SPACE(ch)          true if character is whitespace (e.g. 'isspace'),
-//                                          required for default WORDLEFT/WORDRIGHT handlers
-//    STB_TEXTEDIT_MOVEWORDLEFT(obj,i)   custom handler for WORDLEFT, returns index to move cursor to
-//    STB_TEXTEDIT_MOVEWORDRIGHT(obj,i)  custom handler for WORDRIGHT, returns index to move cursor to
-//    STB_TEXTEDIT_K_WORDLEFT            keyboard input to move cursor left one word // e.g. ctrl-LEFT
-//    STB_TEXTEDIT_K_WORDRIGHT           keyboard input to move cursor right one word // e.g. ctrl-RIGHT
-//    STB_TEXTEDIT_K_LINESTART2          secondary keyboard input to move cursor to start of line
-//    STB_TEXTEDIT_K_LINEEND2            secondary keyboard input to move cursor to end of line
-//    STB_TEXTEDIT_K_TEXTSTART2          secondary keyboard input to move cursor to start of text
-//    STB_TEXTEDIT_K_TEXTEND2            secondary keyboard input to move cursor to end of text
-//
-// Keyboard input must be encoded as a single integer value; e.g. a character code
-// and some bitflags that represent shift states. to simplify the interface, SHIFT must
-// be a bitflag, so we can test the shifted state of cursor movements to allow selection,
-// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow.
-//
-// You can encode other things, such as CONTROL or ALT, in additional bits, and
-// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example,
-// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN
-// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit,
-// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the
-// API below. The control keys will only match WM_KEYDOWN events because of the
-// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN
-// bit so it only decodes WM_CHAR events.
-//
-// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed
-// row of characters assuming they start on the i'th character--the width and
-// the height and the number of characters consumed. This allows this library
-// to traverse the entire layout incrementally. You need to compute word-wrapping
-// here.
-//
-// Each textfield keeps its own insert mode state, which is not how normal
-// applications work. To keep an app-wide insert mode, update/copy the
-// "insert_mode" field of STB_TexteditState before/after calling API functions.
-//
-// API
-//
-//    void stb_textedit_initialize_state(STB_TexteditState *state, int is_single_line)
-//
-//    void stb_textedit_click(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y)
-//    void stb_textedit_drag(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y)
-//    int  stb_textedit_cut(STB_TEXTEDIT_STRING *str, STB_TexteditState *state)
-//    int  stb_textedit_paste(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXTEDIT_CHARTYPE *text, int len)
-//    void stb_textedit_key(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXEDIT_KEYTYPE key)
-//
-//    Each of these functions potentially updates the string and updates the
-//    state.
-//
-//      initialize_state:
-//          set the textedit state to a known good default state when initially
-//          constructing the textedit.
-//
-//      click:
-//          call this with the mouse x,y on a mouse down; it will update the cursor
-//          and reset the selection start/end to the cursor point. the x,y must
-//          be relative to the text widget, with (0,0) being the top left.
-//     
-//      drag:
-//          call this with the mouse x,y on a mouse drag/up; it will update the
-//          cursor and the selection end point
-//     
-//      cut:
-//          call this to delete the current selection; returns true if there was
-//          one. you should FIRST copy the current selection to the system paste buffer.
-//          (To copy, just copy the current selection out of the string yourself.)
-//     
-//      paste:
-//          call this to paste text at the current cursor point or over the current
-//          selection if there is one.
-//     
-//      key:
-//          call this for keyboard inputs sent to the textfield. you can use it
-//          for "key down" events or for "translated" key events. if you need to
-//          do both (as in Win32), or distinguish Unicode characters from control
-//          inputs, set a high bit to distinguish the two; then you can define the
-//          various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit
-//          set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is
-//          clear. STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to
-//          anything other type you wante before including.
-//
-//     
-//   When rendering, you can read the cursor position and selection state from
-//   the STB_TexteditState.
-//
-//
-// Notes:
-//
-// This is designed to be usable in IMGUI, so it allows for the possibility of
-// running in an IMGUI that has NOT cached the multi-line layout. For this
-// reason, it provides an interface that is compatible with computing the
-// layout incrementally--we try to make sure we make as few passes through
-// as possible. (For example, to locate the mouse pointer in the text, we
-// could define functions that return the X and Y positions of characters
-// and binary search Y and then X, but if we're doing dynamic layout this
-// will run the layout algorithm many times, so instead we manually search
-// forward in one pass. Similar logic applies to e.g. up-arrow and
-// down-arrow movement.)
-//
-// If it's run in a widget that *has* cached the layout, then this is less
-// efficient, but it's not horrible on modern computers. But you wouldn't
-// want to edit million-line files with it.

-// USAGE
-//
-//   Include this file in whatever places need to refer to it. In ONE C/C++
-//   file, write:
-//      #define STB_TRUETYPE_IMPLEMENTATION
-//   before the #include of this file. This expands out the actual
-//   implementation into that C/C++ file.
-//
-//   To make the implementation private to the file that generates the implementation,
-//      #define STBTT_STATIC
-//
-//   Simple 3D API (don't ship this, but it's fine for tools and quick start)
-//           stbtt_BakeFontBitmap()               -- bake a font to a bitmap for use as texture
-//           stbtt_GetBakedQuad()                 -- compute quad to draw for a given char
-//
-//   Improved 3D API (more shippable):
-//           #include "stb_rect_pack.h"           -- optional, but you really want it
-//           stbtt_PackBegin()
-//           stbtt_PackSetOversampling()          -- for improved quality on small fonts
-//           stbtt_PackFontRanges()               -- pack and renders
-//           stbtt_PackEnd()
-//           stbtt_GetPackedQuad()
-//
-//   "Load" a font file from a memory buffer (you have to keep the buffer loaded)
-//           stbtt_InitFont()
-//           stbtt_GetFontOffsetForIndex()        -- indexing for TTC font collections
-//           stbtt_GetNumberOfFonts()             -- number of fonts for TTC font collections
-//
-//   Render a unicode codepoint to a bitmap
-//           stbtt_GetCodepointBitmap()           -- allocates and returns a bitmap
-//           stbtt_MakeCodepointBitmap()          -- renders into bitmap you provide
-//           stbtt_GetCodepointBitmapBox()        -- how big the bitmap must be
-//
-//   Character advance/positioning
-//           stbtt_GetCodepointHMetrics()
-//           stbtt_GetFontVMetrics()
-//           stbtt_GetFontVMetricsOS2()
-//           stbtt_GetCodepointKernAdvance()
-//
-//   Starting with version 1.06, the rasterizer was replaced with a new,
-//   faster and generally-more-precise rasterizer. The new rasterizer more
-//   accurately measures pixel coverage for anti-aliasing, except in the case
-//   where multiple shapes overlap, in which case it overestimates the AA pixel
-//   coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If
-//   this turns out to be a problem, you can re-enable the old rasterizer with
-//        #define STBTT_RASTERIZER_VERSION 1
-//   which will incur about a 15% speed hit.
-//
-// ADDITIONAL DOCUMENTATION
-//
-//   Immediately after this block comment are a series of sample programs.
-//
-//   After the sample programs is the "header file" section. This section
-//   includes documentation for each API function.
-//
-//   Some important concepts to understand to use this library:
-//
-//      Codepoint
-//         Characters are defined by unicode codepoints, e.g. 65 is
-//         uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is
-//         the hiragana for "ma".
-//
-//      Glyph
-//         A visual character shape (every codepoint is rendered as
-//         some glyph)
-//
-//      Glyph index
-//         A font-specific integer ID representing a glyph
-//
-//      Baseline
-//         Glyph shapes are defined relative to a baseline, which is the
-//         bottom of uppercase characters. Characters extend both above
-//         and below the baseline.
-//
-//      Current Point
-//         As you draw text to the screen, you keep track of a "current point"
-//         which is the origin of each character. The current point's vertical
-//         position is the baseline. Even "baked fonts" use this model.
-//
-//      Vertical Font Metrics
-//         The vertical qualities of the font, used to vertically position
-//         and space the characters. See docs for stbtt_GetFontVMetrics.
-//
-//      Font Size in Pixels or Points
-//         The preferred interface for specifying font sizes in stb_truetype
-//         is to specify how tall the font's vertical extent should be in pixels.
-//         If that sounds good enough, skip the next paragraph.
-//
-//         Most font APIs instead use "points", which are a common typographic
-//         measurement for describing font size, defined as 72 points per inch.
-//         stb_truetype provides a point API for compatibility. However, true
-//         "per inch" conventions don't make much sense on computer displays
-//         since different monitors have different number of pixels per
-//         inch. For example, Windows traditionally uses a convention that
-//         there are 96 pixels per inch, thus making 'inch' measurements have
-//         nothing to do with inches, and thus effectively defining a point to
-//         be 1.333 pixels. Additionally, the TrueType font data provides
-//         an explicit scale factor to scale a given font's glyphs to points,
-//         but the author has observed that this scale factor is often wrong
-//         for non-commercial fonts, thus making fonts scaled in points
-//         according to the TrueType spec incoherently sized in practice.
-//
-// DETAILED USAGE:
-//
-//  Scale:
-//    Select how high you want the font to be, in points or pixels.
-//    Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute
-//    a scale factor SF that will be used by all other functions.
-//
-//  Baseline:
-//    You need to select a y-coordinate that is the baseline of where
-//    your text will appear. Call GetFontBoundingBox to get the baseline-relative
-//    bounding box for all characters. SF*-y0 will be the distance in pixels
-//    that the worst-case character could extend above the baseline, so if
-//    you want the top edge of characters to appear at the top of the
-//    screen where y=0, then you would set the baseline to SF*-y0.
-//
-//  Current point:
-//    Set the current point where the first character will appear. The
-//    first character could extend left of the current point; this is font
-//    dependent. You can either choose a current point that is the leftmost
-//    point and hope, or add some padding, or check the bounding box or
-//    left-side-bearing of the first character to be displayed and set
-//    the current point based on that.
-//
-//  Displaying a character:
-//    Compute the bounding box of the character. It will contain signed values
-//    relative to <current_point, baseline>. I.e. if it returns x0,y0,x1,y1,
-//    then the character should be displayed in the rectangle from
-//    <current_point+SF*x0, baseline+SF*y0> to <current_point+SF*x1,baseline+SF*y1).
-//
-//  Advancing for the next character:
-//    Call GlyphHMetrics, and compute 'current_point += SF * advance'.
-// 
-//
-// ADVANCED USAGE
-//
-//   Quality:
-//
-//    - Use the functions with Subpixel at the end to allow your characters
-//      to have subpixel positioning. Since the font is anti-aliased, not
-//      hinted, this is very import for quality. (This is not possible with
-//      baked fonts.)
-//
-//    - Kerning is now supported, and if you're supporting subpixel rendering
-//      then kerning is worth using to give your text a polished look.
-//
-//   Performance:
-//
-//    - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
-//      if you don't do this, stb_truetype is forced to do the conversion on
-//      every call.
-//
-//    - There are a lot of memory allocations. We should modify it to take
-//      a temp buffer and allocate from the temp buffer (without freeing),
-//      should help performance a lot.
-//
-// NOTES
-//
-//   The system uses the raw data found in the .ttf file without changing it
-//   and without building auxiliary data structures. This is a bit inefficient
-//   on little-endian systems (the data is big-endian), but assuming you're
-//   caching the bitmaps or glyph shapes this shouldn't be a big deal.
-//
-//   It appears to be very hard to programmatically determine what font a
-//   given file is in a general way. I provide an API for this, but I don't
-//   recommend it.

-//        padding           --  extra "pixels" around the character which are filled with the distance to the character (not 0),
-//                                 which allows effects like bit outlines
-//        onedge_value      --  value 0-255 to test the SDF against to reconstruct the character (i.e. the isocontour of the character)
-//        pixel_dist_scale  --  what value the SDF should increase by when moving one SDF "pixel" away from the edge (on the 0..255 scale)
-//                                 if positive, > onedge_value is inside; if negative, < onedge_value is inside
-//        width,height      --  output height & width of the SDF bitmap (including padding)

-//        return value      --  a 2D array of bytes 0..255, width*height in size
-//
-// pixel_dist_scale & onedge_value are a scale & bias that allows you to make
-// optimal use of the limited 0..255 for your application, trading off precision
-// and special effects. SDF values outside the range 0..255 are clamped to 0..255.
-//
-// Example:
-//      scale = stbtt_ScaleForPixelHeight(22)
-//      padding = 5
-//      onedge_value = 180
-//      pixel_dist_scale = 180/5.0 = 36.0
-//
-//      This will create an SDF bitmap in which the character is about 22 pixels
-//      high but the whole bitmap is about 22+5+5=32 pixels high. To produce a filled
-//      shape, sample the SDF at each pixel and fill the pixel if the SDF value
-//      is greater than or equal to 180/255. (You'll actually want to antialias,
-//      which is beyond the scope of this example.) Additionally, you can compute
-//      offset outlines (e.g. to stroke the character border inside & outside,
-//      or only outside). For example, to fill outside the character up to 3 SDF
-//      pixels, you would compare against (180-36.0*3)/255 = 72/255. The above
-//      choice of variables maps a range from 5 pixels outside the shape to
-//      2 pixels inside the shape to 0..255; this is intended primarily for apply
-//      outside effects only (the interior range is needed to allow proper
-//      antialiasing of the font at *smaller* sizes)
-//
-// The function computes the SDF analytically at each SDF pixel, not by e.g.
-// building a higher-res bitmap and approximating it. In theory the quality
-// should be as high as possible for an SDF of this size & representation, but
-// unclear if this is true in practice (perhaps building a higher-res bitmap
-// and computing from that can allow drop-out prevention).
-//
-// The algorithm has not been optimized at all, so expect it to be slow
-// if computing lots of characters or very large sizes.
