It's been more than 2^31 seconds since 1904.
* include/freetype/tttables.h (TT_Header): Change field types.
* src/sfnt/ttload.c (tt_face_load_generic_header): Updated.
* include/freetype/ftsystem.h: Include FT_TYPES_H.
(*FT_Alloc_Func, *FT_Realloc_Func): Use size_t for the size arguments.
* src/raster/ftmisc.h: Ditto.
* builds/amiga/src/base/ftsystem.c, builds/unix/ftsystem.c,
* builds/vms/ftsystem.c, src/base/ftsystem.c (ft_alloc, ft_realloc):
Use size_t for the size arguments.
* src/base/ftdbgmem.c (ft_mem_debug_alloc, ft_mem_debug_realloc): Use
FT_Offset, aka size_t, for the size arguments.
Before this commit we had code like
(FT_Bool)( globals->glyph_styles[gindex] & 0x8000)
Since `FT_Bool' is defined to be an `unsigned char', the code
evaluated to something like
(unsigned char)( 0x8532 & 0x8000)
which in turn expanded to
(unsigned char)( 0x8000)
and finally yielded 0x00 – i.e., false – not as expected.
Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>.
* include/freetype/fttypes.h (FT_BOOL): Add a comparison against
zero so that we always have a Boolean expression.
*/*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where
possible.
These public API functions(!) were always undocumented and have
escaped all clean-up efforts until now.
* include/freetype/ftoutln.h (FT_Outline_New_Internal,
FT_Outline_Done_Internal): Removed.
* src/base/ftoutln.h (FT_Outline_New_Internal,
FT_Outline_Done_Internal): Merge into...
(FT_Outline_New, FT_Outline_Done): ... these functions.
* docs/README: Updated.
* include/freetype/fterrors.h (FT_INCLUDE_ERR_PROTOS,
FT_ERR_PROTOS_DEFINED): Undefine `FT_INCLUDE_ERR_PROTOS' after
checking it and introduce a new macro that takes proper care of
multiple-inclusion protection.
* include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap):
Change return type.
* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Return the bitmap
size assessment.
* src/raster/ftrend1.c (ft_raster1_render): Use it to refuse the
rendering of enourmous or far-fetched outlines.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto.
* include/freetype/internal/ftcalc.h (ADD_INT64, SUB_INT64,
MUL_INT64, DIV_INT64) [FT_LONG64]: New macros.
* src/base/ftcalc.c (ft_corner_orientation) [FT_LONG64]: Use
`SUB_INT64' and `MUL_INT64'.

It sometimes makes sense to suppress tracing informations, for
example, if it outputs identical messages again and again.
* include/freetype/internal/ftdebug.h: Make `ft_trace_levels' a
pointer.
(FT_Trace_Disable, FT_Trace_Enable): New declarations.
* src/base/ftdebug.c (ft_trace_levels): Rename to...
(ft_trace_levels_enabled): ... this.
(ft_trace_levels_disabled): New array.
(ft_trace_levels): New pointer.
(FT_Trace_Disable, FT_Trace_Enable): Implement.
(ft_debug_init): Updated.
We no longer use predefined _DLL, which can be defined for static
builds too with /MD. We use DLL_EXPORT and DLL_IMPORT instead,
following libtool convention.
* CMakeLists.txt [WIN32], builds/windows/vc2010/freetype.vcxproj:
Define DLL_EXPORT manually.
* include/freetype/config/ftconfig.h, builds/unix/ftconfig.in,
builds/vms/ftconfig.h, builds/windows/vc2010/index.html,
src/base/ftver.rc: /_DLL/d, s/FT2_DLLIMPORT/DLL_IMPORT/.
This is a valid encoding tag for BDF, PCF, and Windows FNT, and
there is no reason to disallow it for these formats.
* src/base/ftobjs.c (FT_Select_Charmap): Implement it.
