[Description]
Adds extended dialog properties into a dialog box.

[Explanation]
DialogAddXFlags adds extended dialog properties to the dialog structure
associated with the handle <I>Handle</I>.<BR>
The XFLAGS item defines an array of four extended unsigned short flags (i.e.
<I>xFlags1</I>, <I>xFlags2</I>, <I>xFlags3</I>, <I>xFlags4</I>.) Currently only
<I>xFlags1</I> is used: the three remaining values should always be set to zero
for future compatibility.
<BR><BR>
The order of item creation is very important, as it automatically gives each
item an identification number (the first created item will get an
identification number of 0, the second one will get 1, and so on). Every
function that creates an item (i.e. every function beginning with
'DialogAdd...') will increase this identification number.
<BR><BR>
The parameter <I>xFlags1</I> may contain a combination of the following flags,
defined in the <A HREF="$$LINK(DialogXFlags)">DialogXFlags</A> enumeration:
<TABLE BORDER CELLPADDING="3">
<TR>
<TD>XF_ALLOW_VARLINK</TD>
<TD>Setting this extended <I>xflag</I> allows all EDIT (=request) items in the
dialog box to allow the [VAR-LINK] key to be activated within the dialog box
and to paste results to the edit item. If this <I>xflag</I> or
XF_VARLINK_SELECT_ONLY is not set, then when [VAR-LINK] is pressed in a dialog
box, the dialog will be closed and VAR-LINK will be activated.</TD>
</TR>
<TR>
<TD>XF_NO_ALPHA_LOCK</TD>
<TD>On the TI-89, Alpha-Lock is turned on for all dialog boxes with edit items.
Setting this extended <I>xflag</I> disables this feature.</TD>
</TR>
<TR>
<TD>XF_VARLINK_SELECT_ONLY</TD>
<TD>This <I>xflag</I> is similar to XF_ALLOW_VARLINK except thet the user may
not make any variable changes inside VAR-LINK (like deleting, copying,
renaming, or locking variables).</TD>
</TR>
<TR>
<TD>XF_TE_REPAINT</TD>
<TD>This <I>xflag</I> is unknown for the moment. Do not use. </TD>
</TR>
</TABLE>
<BR>
The parameter <I>flags</I> can be zero or DF_SCREEN_SAVE if you wish the dialog
code to save the area underneath the dialog box when it is started and to
return DB_MEMFULL if it cannot. Note that if you use this flag, the item must
be the first one to be created. These flags are defined in the
<A HREF="$$LINK(DialogFlags)">DialogFlags</A> enumeration.
<BR><BR>
DialogAddXFlags returns <A HREF="$$LINK(alloc.h/H_NULL)">H_NULL</A> in case
of an error, may return <A HREF="$$LINK(DialogMessages)">DB_MEMFULL</A> if you
used <A HREF="$$LINK(DialogFlags)">DF_SCREEN_SAVE</A>, else returns
<I>Handle</I>. This routine (as well as all other 'DialogAdd...' routines) may
cause heap compression.
<BR><BR>
DialogAddXFlags is in fact a macro created for your convenience. It calls
<A HREF="$$LINK(DialogAdd)">DialogAdd</A> with D_XFLAGS as the <I>ItemType</I>
parameter and with zero passed to the <I>x</I> and <I>y</I> parameters. (These
parameters are ignored when you use D_XFLAGS as the <I>ItemType</I>.)
