- [gzip] Improve building with external zlib (#49673).
- Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
- the following error.
- ftgzip.c
- zlib-1.2.8\zlib.h(86): error C2061:
- syntax error: identifier 'z_const'

- 'msg': not in formal parameter list

- zlib-1.2.8\zlib.h(877): fatal error C1003:
- error count exceeds 100; stopping compilation
- The error happens because FreeType keeps an own copy of zlib-1.1.4
- under `src/gzip'. When building `src/gzip/ftgzip.c' with
- FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
- #include <zlib.h>
- which correctly finds an external `zlib.h', but `zlib.h' itself has
- a line
- #include "zconf.h"
- which makes Visual Studio 2015 find `src/gzip/zconf.h' while

- Introduce a way of quickly retrieving (embedded) bitmap metrics.
- `FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph

- FreeType in 2011) that I forgot to apply.
- https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
- Prepend the foundry name plus a space to the family name. There are
- many fonts just called `Fixed' which look completely different, and
- which have nothing to do with each other. When selecting `Fixed' in
- KDE or Gnome one gets results that appear rather random, the style
- changes often if one changes the size and one cannot select some
- fonts at all.
- We also check whether we have `wide' characters; all put together,
- we get family names like `Sony Fixed' or `Misc Fixed Wide'.

- Without this patch, a loca sequence like `0 100000 0 100000 ...',
- where value 100000 is larger than the `glyf' table size, makes
- FreeType handle the whole `glyf' table as a single glyph again and

- [smooth] Simplify span rendering more.
- It turns out that there is significant cost associated with `FT_Span'
- creation and calls to `gray_render_span' because it happens so
- frequently. This removes these steps from our internal use but leaves
- it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
- is about 5%.
- * src/smooth/ftgrays.c (gray_render_span): Removed. The code is
- migrated to...
- (gray_hline): ... here.
- 2016-08-30 Alexei Podtelezhnikov <apodtele@gmail.com>
- [smooth] Streamline pixmap drawing a bit more.
- Zero coverage is unlikely (1 out of 256) to warrant checking. This
- gives 0.5% speed improvement in rendering simple glyphs.
- * src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks.
- 2016-08-29 Alexei Podtelezhnikov <apodtele@gmail.com>
- [smooth] Streamline pixmap drawing.
- This gives 2% speed improvement in rendering simple glyphs.
- * src/smooth/ftgrays.c (TPixmap): Reduced pixmap descriptor with a
- pointer to its bottom-left and pitch to be used in...
- (gray_TWorker): ... here.

- (gray_raster_render): .. to here.
- 2016-08-27 Alexei Podtelezhnikov <apodtele@gmail.com>

- 2016-08-22 Alexei Podtelezhnikov <apodtele@gmail.com>

- (gray_TWorker): Remove span buffer and related fields.
- (gray_sweep, gray_hline): Updated.

- * src/smooth/ftgrays.c (gray_hline): Fix uninitialized access.
- 2016-08-10 Werner Lemberg <wl@gnu.org>
- [sfnt] Use correct type for `italicAngle' field (#48732).
- * src/sfnt/ttload.c (tt_face_load_post): Fix types.
- 2016-08-06 Jon Spencer <jon@jonspencer.ca>
- [sfnt] Fix `FT_Get_Advance' for bitmap strikes.
- `FT_Get_Advance' returns 0 for bitmap fonts. It first gets the
- advance value from the font table and then scales it by the
- `font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't
- set that value for bitmap fonts and the advance gets scaled to zero.
- Taken from
- https://github.com/behdad/harfbuzz/issues/252
- * src/sfnt/ttsbit.c (tt_face_load_strike_metrics)
- <TT_SBIT_TABLE_TYPE_EBLC>: Set scale values.

- Updated.
- 2016-07-29 Werner Lemberg <wl@gnu.org>
- [sfnt, truetype] Don't abort on invalid `maxComponentDepth'.
- Since 2016-05-16 we detect infinite recursion directly.
- * src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust
- `maxComponentDepth'.
- * src/truetype/ttgload.c (load_truetype_glyph): Don't abort if
- `maxComponentDepth' is not valid. Instead, simply adjust its value
- and emit a tracing message.
- 2016-07-26 Werner Lemberg <wl@gnu.org>
- * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Minor.
- No functional change.
- 2016-07-22 Hin-Tak Leung <htl10@users.sourceforge.net>
- [truetype] Record the end of IDEFs.
- To match the logic in FDEF. The value of the end is only used for
- bound-checking in `Ins_JMPR', so it may not have been obvious that
- it was not recorded. Tested (as part of Font Validator 2.0) all the
- fonts on Fedora and did not see any change.
- * src/truetype/ttinterp.c (Ins_IDEF): Updated.
- 2016-07-19 Werner Lemberg <wl@gnu.org>

- 2016-07-17 Werner Lemberg <wl@gnu.org>
- [truetype] Add support for Apple's
- GETDATA[], opcode 0x92
- bytecode instruction. It always returns 17, and we have absolutely
- no idea what it is good for...
- * src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated.
- (Ins_GETDATA): New function.
- (TT_RunIns): Add it.
- 2016-07-16 Werner Lemberg <wl@gnu.org>
- [truetype] Add bytecode support for GX variation fonts.
- This commit implements undocumented (but confirmed) stuff from
- Apple's old bytecode engine.
- GETVARIATION[], opcode 0x91
- This opcode pushes normalized variation coordinates for all axes
- onto the stack (in 2.14 format). Coordinate of first axis gets
- pushed first.
- GETINFO[], selector bit 3
- If GX variation support is enabled, bit 10 of the result is set
- to 1.

- [truetype] Make all glyphs in `Zycon' GX font work.
- * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary
- tests.
- 2016-07-16 Werner Lemberg <wl@gnu.org>
- [truetype] Fix GX delta tracing.
- * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace
- relative point movements.
- 2016-07-16 Behdad Esfahbod <behdad@behdad.org>
- [truetype] More fixes for GX.
- This finally fixes the rendering of the cyclist and the lizard in
- the `Zycon' font.
- * src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point
- index is always cumulative.
- (tt_handle_deltas): Rename to...
- (tt_interpolate_deltas): ... This.
- Add new parameter for output point array.
- Update caller.
- (TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds
- the intermediate results of `tt_interpolate_deltas' that are to be
- added to `outline->points'.
- 2016-07-15 Werner Lemberg <wl@gnu.org>
- * src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.

- Reported by Alexei.
- 2016-07-16 Nikolaus Waxweiler <madigens@gmail.com>
- * src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error.
- Problem reported by Hin-Tak Leung.
- 2016-07-15 Werner Lemberg <wl@gnu.org>
- [autofit] Update and improve segment and edge tracing.
- * src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace
- `delta' also.
- Don't show first point of segment as a replacement for `pos'; this
- is (a) misleading, since the difference to `pos' can be almost
- arbitrarily large in corner cases, and (b) it is better to have all
- segment data in font units instead of a single value given in output
- space coordinates.
- Improve layout.
- (af_glyph_hints_dump_edges): Show px->units and units->px conversion
- values for convenience.
- Improve layout.
- 2016-07-15 Werner Lemberg <wl@gnu.org>
- [autofit] For edges, reject segments wider than 1px (#41334).

- 2016-07-14 Behdad Esfahbod <behdad@behdad.org>
- [truetype] Fix gxvar delta interpolation.
- The coordinates of the base font should be used for interpolation
- purposes, NOT the current points (i.e., the result of accumulation
- of previous deltas).
- * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize
- `points_org' before looping over all tuples.
