We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.
*/*: Replace
#include FOO_H
with
#include <freetype/foo.h>
or something similar. Also update the documentation.
These have not been used in a very, very long time, so better remove
them. A corresponding patch will be submitted to the
`freetype2-demos' repository.

* src/cff/cffparse.c (destrict_c2s_item): Guard function with

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.
For bitmap fonts, `FT_Load_Glyph' should either return an error or
not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this
case `FT_Load_Glyph' calls into the auto-hinter which calls back
into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which
marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path
(even though it doesn't have any path). It appears that the
auto-hinter should not be called when the face doesn't have
outlines. The current test for using the auto-hinter in
`FT_Load_Glyph' checks if the driver supports scalable outlines, but
not if the face supports scalable outlines.
* src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have
scalable outlines.
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/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.
* src/base/ftobjs.c (pixel_modes): Move this array to top level
from ...
(FT_Load_Glyph): ... here.
(FT_Render_Glyph_Internal): Use `width' x `height' in trace message.
Use `pixel_modes'.
* src/base/ftutil.c (ft_mem_alloc, ft_mem_realloc): Only call
`FT_MEM_ZERO' if we actually have a buffer.
(ft_mem_dup): Only call `ft_memcpy' if we actually have a buffer.
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,

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.
Taken from patch #9667, written by Steve Langasek
<vorlon@debian.org>.
This fixes a build failure (most probably a bug in gcc) on ppc64el
when building with -O3.
* src/base/ftcalc.c (FT_Matrix_Check): New base function to properly
reject degenerate font matrices.
* include/freetype/internal/ftcalc.h: Updated.
* src/cff/cffparse.c (cff_parse_font_matrix), src/cid/cidload.c
(cid_parse_font_matrix), src/type1/t1load.c (t1_parse_font_matrix),
src/type42/t42parse.c (t42_parse_font_matrix): Use
`FT_Matrix_Check'.
This function facilitates access to full capabilities of FreeType
rendering engine for custom glyphs. This can be quite useful for
consistent rendering of mathematical and chemical formulas, e.g.
https://bugs.chromium.org/p/chromium/issues/detail?id=757078
* include/freetype/ftglyph.h, src/base/ftglyph.c (FT_New_Glyph): New
function.
Still missing: Support for negative bitmap pitch and subpixel offset
of source bitmap.
* include/freetype/ftbitmap.h, src/base/ftbitmap.c
(FT_Bitmap_Blend): New function.
This solution doesn't store any data in an `FT_GlyphSlot' object.
* include/freetype/freetype.h (FT_LayerIterator): New structure.
(FT_Get_Color_Glyph_Layer): New function.
* include/freetype/internal/sfnt.h (TT_Get_Colr_Layer_Func): New
function type.
(SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): Add it.
* src/base/ftobjs.c (FT_Get_Color_Glyph_Layer): Implement it.
* src/sfnt/ttcolr.c (tt_face_get_colr_layer): New function.
* src/sfnt/ttcolr.h: Updated.
* src/sfnt/sfdriver.c (sfnt_interface): Updated.
