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.
* include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use
`logical not' operator instead of negation. The idea is that `~'
returns exactly the data type enforced by the cast to a pointer (be
it 32bit or 64bit or whatever), while a negative integer has not
this flexibility.
* src/cache/ftccmap.c (FTC_CMAP_UNKNOWN): Ditto.
* src/truetype/ttgxvar.c (ALL_POINTS, TT_Get_MM_Var): Ditto.
* src/type/t1load.c (T1_Get_MM_Var): Ditto.
(parse_blend_axis_types): Use cast.
* src/bdf/bdflib.c (_bdf_readstream): Use cast.
* src/bdf/bdflib.c (_bdf_list_ensure): Bring code in sync with
comment before `_bdf_list_split', this is, really allocate at least
five `field' elements.
* src/bdf/bdflib.c (_bdf_parse_glyphs) <DWIDTH, BBX>: Abort if
_BDF_ENCODING isn't set. We need this because access to the `glyph'
variable might be undefined otherwise.
ENCODING now covers the whole Unicode range.
Note, however, that this change is quite expensive since it
increases the size of three arrays by almost 400kByte in total. The
right fix is to replace the logic with something smarter.
Additionally, there exist very old BDFs for three-byte CCCII
encoding which exceeds the range of Unicode (another reason to have
a smarter logic).
* src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'
arrays.
* src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array.
* src/bdf/bdflib.c (_bdf_readstream): Use special error code to
indicate a redo operation.
(_bdf_parse_start): Handle `CHARS' keyword here too and pass current
input line to `_bdf_parse_glyph'.
* include/freetype/fterrdef.h
(BDF_Err_Missing_Fontboundingbox_Field): New error code.
* src/bdf/bdflib.c (_bdf_parse_start): Check for missing
`FONTBOUNDINGBOX' field.
Avoid memory leak if there are multiple `FONT' lines (which is
invalid but doesn't hurt).
gracefully.
(_bdf_set_default_spacing): Increase `name' buffer size to 256 and
issue an error for longer names.
(_bdf_parse_glyphs): Limit allowed number of glyphs in font to the
number of code points in Unicode.
Fix miscellaneous compiler warnings.
* freetype2/include/freetype/internal/ftobjs.h: close
comment with `*/' to avoid `/* in comment' compiler warning.
* freetype2/src/base/ftdbgmem.c (ft_mem_table_get_source): Turn
cast `(FT_UInt32)(void*)' into `(FT_UInt32)(FT_PtrDist)(void*)'
since on 64-bit platforms void* is larger than FT_UInt32.
* freetype2/src/base/ftobjs.c (t_validator_error): cast
away volatileness of argument to ft_longjmp. Spotted by
Werner `Putzfrau' Lemberg.
* freetype2/src/bdf/bdflib.c (bdf_load_font): initialize
local variable `lineno'.
* freetype2/src/gxvalid/gxvmod.c (classic_kern_validate):
mark local variable `error' volatile.
used to reduce the amount of heap size required to only test wether
we're dealing with a BDF font (the old code allocated 64 Kb right
before any test).
* src/lzw/ftlzw.c (FT_Stream_OpenLZW): modified the function to check
the LZW header before doing anything else. This helps avoid un-necessary
heap allocations (400 Kb of heap memory for the LZW decoder ! Oh my !)
* src/gzip/ftgzip.c (FT_Stream_OpenGZip): ditto for the .gz decoder,
though the code savings is smaller.
