* include/freetype/internal/ftdebug.h (FT_Trace): Remove comma in
enum to avoid compiler warnings.
2002-02-21 David Turner <david@freetype.org>
* include/freetype/internal/ftdebug.h, src/base/ftdebug.c: modified
the debug sub-system initialization. trace levels can now be specified
within the "FT2_DEBUG" environment variable. See the comments within
"ftdebug.c" for more details
Modified the debug sub-system initialization. Trace levels can now
be specified within the "FT2_DEBUG" environment variable. See the
comments within "ftdebug.c" for more details.
* include/freetype/internal/fttrace.h: new file to define the trace
levels used for debugging. it is used both to define enums and
toggle names for FT2_DEBUG
* src/base/ftdebug.c: (FT_SetTraceLevel): Removed.
(ft_debug_init): New function.
(ft_debug_dummy): Removed.
Updated to changes in ftdebug.h
* include/freetype/internal/ftdebug.h: Always define
FT_DEBUG_LEVEL_ERROR if FT_DEBUG_LEVEL_TRACE is defined.
(FT_Assert): Renamed to ...
(FT_ASSERT): This.
Some stuff from ftdebug.h has been moved to ...
* src/base/ftobjs.c, src/base/ftstream.c: FT_Assert renamed to

trace levels used for debugging. It is used both to define enums

* include/freetype/internal/internal.h: Updated.
* include/freetype/internal/ftextend.h, src/base/ftextend.c,
src/base/Jamfile, src/base/rules.mk: removing "ftextend" from the
library, since it is now completely obsolete..
* src/base/ftobjs.c, src/base/ftstream.c: Updated.
* include/freetype/fterrors.h: adding "#undef FT_ERR_CAT" to avoid
warnings with certain compilers (like LCC)
* include/freetype/internal/ftextend.h, src/base/ftextend.c:
Removed. Both files are now completely obsolete.
* src/base/Jamfile, src/base/rules.mk: Updated.
* src/pshinter/pshalgo2.c: renaming 'print_zone' to 'psh2_print_zone'
to avoid errors during compilation of debug library
* include/freetype/fterrors.h: Adding "#undef FT_ERR_CAT" and
`#undef FT_ERR_XCAT" to avoid warnings with certain compilers (like
LCC).
* src/pshinter/pshalgo2.c (print_zone): Renamed to ...
(psh2_print_zone): This to avoid errors during compilation of debug
library.
* src/smooth/ftgrays.c (FT_COMPONENT): Change definition to as
`trace_smooth'.
