Everything is guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT.
* src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Don't handle MM.
* src/cff/cffdrivr.c: Include FT_SERVICE_METRICS_VARIATIONS_H.
(cff_get_advances): Test for HVAR and VVAR.
* src/truetype/ttdriver.c (tt_get_advances): Test for HVAR and VVAR.
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.
(FT_Outline_Decompose): Decorate with tracing messages.
* src/smooth/ftgrays.c [DEBUG_GRAYS]: Replace with
FT_DEBUG_LEVEL_TRACE.
[_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: Include stdio.h and
stdarg.h.
(FT_TRACE) [_STANDALONE_]: Remove.
(FT_Message) [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: New function.
(FT_TRACE5, FT_TRACE7) [_STANDALONE_]: New macros.
(FT_ERROR) [_STANDALONE_]: Updated.
(gray_hline) [FT_DEBUG_LEVEL_TRACE]: Fix condition.
Use FT_TRACE7.
(gray_dump_cells): Make it `static void'.
(graay_convert_glyph): Use FT_TRACE7.
(FT_Outline_Decompose) [_STANDALONE_]: Synchronize with version in
ftoutln.c.
* src/base/ftadvanc.c (FT_Get_Advance, FT_Get_Advances): Use
FT_ERROR_BASE.
Other minor modifications.
