* src/sfnt/ttsbit.c (tt_face_load_sbit) [TT_SBIT_TABLE_TYPE_SBIX]:
Accept overlay format also, but emit warning message in that case.
(tt_sbit_decoder_load_metrics): Add missing newline to error
message.
(tt_sbit_load_sbix_image): Add `rgbl' graphic type (as used on iOS
7.1) to the list of unsupported formats.
Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.
* src/sfnt/sfobjs.c (sfnt_load_face): Return correct `bsize->width'
value if the font lacks an `OS/2' table.
We simply synthesize a SFNT from the WOFF, create a memory stream
for the new data, and load the SFNT as usual.
Does NOT add any API to access WOFF metadata or private blocks.
* include/freetype/internal/tttypes.h (WOFF_HeaderRec,
WOFF_TableRec): New structures.
* include/freetype/tttags.h (TTAG_wOFF): New macro.
* src/base/ftobjs.c (FT_Open_Face): Set `stream' after calling
`open_face'.
* src/sfnt/sfobjs.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Include
`FT_GZIP_H'.
(WRITE_BYTE, WRITE_USHORT, WRITE_ULONG): New temporary macros for
writing to a stream.
(sfnt_stream_close, compare_offsets, woff_open_font): New functions.
(sfnt_open_font): Handle `TTAG_wOFF'.
(sfnt_init_face): Set `stream' after calling `sfnt_open_font'.
* src/truetype/ttobjs.c (tt_face_init): Set `stream' after calling
`sfnt->init_face'.
* src/base/ftobjs.c (open_face): Use a pointer to FT_Stream as an
argument so that a changed stream survives.
Update callers.
* src/sfnt/sfobjs.c (sfnt_load_face): Apple's `sbix' color bitmaps
are rendered scaled and then the `glyf' outline rendered on top. We
don't support that yet, so just ignore the `glyf' outline and
advertise it as a bitmap-only font.
* src/sfnt/ttsbit.c (tt_face_load_strike_metrics)
[TT_SBIT_TABLE_TYPE_SBIX]: Return metrics in 26.6 units.
(tt_face_load_sbix_image): Typo.
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.
Previously, FreeType misleadingly returned
FT_Err_Unknown_File_Format if a module was missing (or a test was
missing completely).
* include/freetype/fterrdef.h (FT_Err_Missing_Module): Define.
* src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c

* src/type1/t1afm.c (T1_Read_Metrics), src/type/t1objs.c
(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Remove now
redundant test for `psaux'.
* src/sfnt/sfobjs.c (sfnt_load_face): Test for bitmap strikes before
setting metrics and bbox values. This ensures that the check for a
font with neither a `glyf' table nor bitmap strikes can be performed
early enough to set metrics and bbox values too.
src/smooth/ftgrays.c, src/base/ftobjc.s, src/sfobjs.c:

errors in the bytecode interpreter only.
nor bitmaps can be considered as containing space `glyphs' only.
* src/truetype/ttpload.c (tt_face_load_loca): Handle the case where
a `glyf' table is missing.
* src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no
`glyf' table but a non-zero `loca' entry.
(tt_loader_init): Handle missing `glyf' table.
* src/base/ftobjs.c (FT_Load_Glyph): Undo change 2008-12-05.
* src/sfnt/sfobjs.c (sfnt_load_face): A font with neither outlines
nor bitmaps is scalable.
0x100 instead of 0x10000; the latter value is already occupied by
FT_LOAD_TARGET_LIGHT. Bug reported by James Cloos.
Handle SFNT with neither outlines nor bitmaps. This fixes Savannah
bug #25010.
* src/base/ftobjs.c (FT_Load_Glyph): Reject fonts with neither
outlines nor bitmaps.
* src/sfnt/sfobjs.c (sfnt_load_face): Don't return an error if there
is no table with glyphs.
* src/sfnt/ttload.c (tt_face_lookup_table): Improve debugging
message.
Other minor cosmetics.

support for bit 8 in the `OS/2' table. MS is already using this;
hopefully, this becomes part of OpenType 1.5.
Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
(WWS_SUBFAMILY).
Fonts without a cmap must be handled correctly by FreeType (anything
else would be a bug).
* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
[FT_DEBUG_LEVEL_TRACE]: Improve tracing message.
