include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor
beautifying.
* include/freetype/ftadvanc.h, include/freetype/ftgasp.h,
include/freetype/ftlcdfil.h: Protect against FreeType 1.
Some other minor fixes.
* devel/ftoption.h: Synchronize with
include/freetype/config/ftoption.h.
Formatting, documentation improvements.
builds/unix/ftconfig.in, include/freetype/freetype.h,
src/base/ftcalc.c:
Make FT_MulFix an inlined function. Also provide an assembler
implementation for ARM architectures. this is done to speedup
FreeType a little (on x86 3% when loading+hinting, 10% when
rendering, ARM savings are more important though).
Disable this by undefining FT_CONFIG_OPTION_INLINE_MULFIX in
ftconfig.h

src/base/Jamfile, src/base/rules.mk, src/cff/cffdrivr.c,

src/truetype/ttgload.h, src/truetype/ttgload.c, src/type1/t1driver.c,
src/type1/t1gload.h, src/type1/t1gload.c:
Add a new header named FT_ADVANCES_H declaring some new APIs
to extract the advances of one or more glyphs without necessarily
loading their outlines. Also provide 'fast loaders' for the
TrueType, Type1 and CFF font drivers (more to come later)
* autogen.sh: add checks for minimum version of the 'autotools'
stuff.
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 ...)'.
* docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
it.
=========================
Tag sources with `VER-2-3-7'.
* docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
version number to 2.3.7.
* README, Jamfile (RefDoc), builds/win32/visualc/index.html,
builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj,
builds/win32/visualce/index.html,
builds/win32/visualce/freetype.dsp,
builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.
* 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.
