assume that the first argument on the stack is the bottom-most
element. Two reasons:
o According to people from Adobe it is missing in the Type 2
specification that pushing of additional, superfluous arguments
on the stack is prohibited.
o Acroread in general handles fonts differently, namely by popping
the number of arguments needed for a particular operand (as a PS
interpreter would do). In case of buggy fonts this causes a
different interpretation which of the elements on the stack are
superfluous and which not.
Since there are CFF subfonts (embedded in PDFs) which rely on
Acroread's behaviour, FreeType now does the same.
tt_cmap4_char_map_binary): Handle fonts which treat the last segment
specially. According to the specification, such fonts would be
invalid but acroread accepts them.
newer.
* configure: zsh doesn't like ${1+"$@"}.
Update needed GNU make version.
* builds/toplevel.mk: Check for `$(eval ...)'.

it.

Tag sources with `VER-2-3-7'.

version number to 2.3.7.

* include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.
* builds/unix/configure.raw (version_info): Set to 9:18:3.
* docs/release: Updated.
Horizontal_Gray_Sweep_Drop): Test for intersections which
degenerate to a single point can be ignored; this has been confirmed
by Greg Hitchcock from Microsoft. (This was commented out code.)
* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
Draw_Sweep): No-dropout mode is value 2, not value 0.
(Draw_Sweep): Really skip dropout handling for no-dropout mode.
Pass dropout rules from the TT bytecode interpreter to the
rasterizer; temporarily this is enabled only if
`USE_SCAN_CONVERSION_RULES' is defined.
* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline.
* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
OpenType specification.
Fix mode 4 computation.
(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
* src/truetype/ttgload.c (TT_Load_Glyph)
[USE_SCAN_CONVERSION_RULES]: Convert scan conversion mode to
FT_OUTLINE_XXX flags.
* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
`dict->units_per_em' value before assigning it to
`cffface->units_per_EM'. Otherwise, CFFs without subfonts are be
scaled incorrectly if the font matrix is non-standard. This fixes
Savannah bug #23630.

bug #23497.
* builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
as a replacement for OutputDebugStringA (which WinCE doesn't have).
Update all callers.
(ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
environment variables.
of the graphics state for subglyphs to...
(TT_Hint_Glyph): This function.
Hinting instructions for a composite glyph apparently refer to the
just hinted subglyphs, not the unhinted, unscaled outline. This
seems to fix Savannah bugs #20973 and (at least partially) #23310.
