This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.
No change in functionality, of course.
I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if
`POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are
missing.
* docs/CHANGES: Document it.
For functions querying a face, bits 16-30 of the face index can hold
the named instance index if we have a GX font. The indices start
with value 1; value 0 indicates font access without GX variation
data.
* include/freetype/freetype.h (FT_FaceRec): Update documentation.
* include/freetype/internal/sfnt.h: Ditto.
* src/sfnt/sfobjs.c (sfnt_init_face)
[TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and
do argument checks.
(sfnt_load_face): Updated.
* src/truetype/ttobjs.c (tt_face_init)
[TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Use named instance, overwriting
the style name.
* src/base/ftobjs.c (open_face_from_buffer,
open_face_PS_from_sfnt_stream): Updated.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Updated.
* src/cff/cffload.c (cff_font_load): Updated.
* src/cff/cffobjs.c (cff_face_init): Make function exit early for
pure CFF fonts if `font_index < 0'.
Updated.
* src/cid/cidobjs.c (cid_face_init): Updated.
* src/pcf/pcfdrivr.c (PCF_Face_Init): Updated.
* src/pfr/pfrobjs.c (pfr_face_init): Updated.
* src/type1/t1objs.c (T1_Face_Init): Updated.
* src/type42/t42objs.c (T42_Face_Init): Updated.
* src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init):
Updated.
* docs/CHANGES: Updated.
* src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Only accept
positive values from header.
Check overflow.
* src/base/ftoutln.c (SCALED): Correctly handle left-shift of
negative values.
* src/bdf/bdf.h (_bdf_glyph_modified, _bdf_set_glyph_modified,
_bdf_clear_glyph_modified): Use unsigned long constant.
* src/bdf/bdfdrivr.c (BDF_Size_Select, BDF_Glyph_Load): Don't
left-shift values that can be negative.
* src/pcf/pcfdrivr.c (PCF_Size_Select, PCF_Glyph_Load): Don't
left-shift values that can be negative.
* src/raster/ftraster.c (SCALED): Correctly handle left-shift of
negative values.
* src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Don't left-shift
values that can be negative.
* src/truetype/ttgload.c (TT_Load_Composite_Glyph,
compute_glyph_metrics, load_sbit_image): Don't left-shift values
that can be negative.
Suggested by Akira Tagoh, see
http://lists.gnu.org/archive/html/freetype/2013-09/msg00030.html
* src/bdf/bdfdrivr.c (BDF_Face_Init): Return Invalid_Argument error
when the font could be opened but non-zero face_index is given.
* src/pcf/pcfdrivr.c (PCF_Face_Init): Ditto.
* src/type42/t42objs.c (T42_Face_Init): Remove unrequired FT_UNUSED
macro for face_index because it is validated in later.
Previously, the loading of a glyph was traced at level 4, if at all.
With this change, all font loading routines emit a tracing message
at level 1, making it easier to select tracing output (for example
using F2_DEBUG="any:1 afhints:7 aflatin:7").
* src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message.
* src/cff/cffdrivr.c (cff_glyph_load): Ditto.
* src/cff/cffgload.c (cff_decoder_prepare): Improve tracing
messages.
* src/cid/cidgload.c (cid_load_glyph): Use level 1 for tracing
message.
* src/pcf/pcfdrivr.c (PCF_Glyph_Load): Ditto.
* src/pfr/pfrobjs.c (pfr_slot_load): Add tracing message.
* src/truetype/ttgload.c (TT_Load_Glyph): Ditto.
* src/type1/t1gload.c (T1_Load_Glyph): Ditto.
* src/type42/t42objs.c (T42_GlyphSlot_Load): Ditto.
* src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.
To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code. Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

test for a valid glyph index must be deferred to the font drivers.
This patch fixes Savannah bug #18301.
* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.

src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c
(FNT_Load_Glyph): Check validity of `glyph_index'.
the warp hinter isn't active (it shouldn't, still experimental)
* Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
and "otvalid" from the list of modules that are linked statically
to a given FreeType library. Functionality has been moved to the
"ftvalid" CVS module.
note also that current Make-based build system still compiles the
modules though...
* include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
which controls the definitions of the memory management functions
to avoid warnings with recent versions of GCC. this macro is
only here to be disabled, in case we detect problems with the
new scheme.
NOTE: disable macro to use the memory debugger. this will be fixed
later !!
