Complete redesign of error codes. Please check ftmoderr.h for more details. * include/freetype/internal/cfferrs.h, include/freetype/internal/tterrors.h, include/freetype/internal/t1errors.h: Removed.

Renamed "ftnames.h" to "ftsnames.h", and FT_NAMES_H to FT_SFNT_NAMES_H. * docs/docmaker.py: Added generation of INDEX link in table of contents. * INSTALL, docs/BUILD: Updated documentation to indicate that the compilation process has changed slightly (no more `src' required in * builds/*/*-def.mk: Changed the objects directory from "obj" to "objs". * include/freetype/config/ftheader.h: Removed obsolete macros like FT_SOURCE_FILE, etc. and added cache-specific macro definitions that were previously defined in <freetype/ftcache.h>. Added comments to be included in a new API Reference section. * src/*/*: Removed the use of FT_SOURCE_FILE, etc. Now, each component needs to add its own directory to the include path at compile time. Modified all "rules.mk" and "descrip.mms" accordingly. * src/cid/cidobjs.c, src/cid/cidload.c, src/pcf/pcfread.c, src/type1/t1load.c, src/type1/t1objs.c: Added a few casts to remove compiler warnings in pedantic modes. * include/config/ft2build.h, include/config/ftheader.h: The file top-level <ft2build.h>. * include/config/ftheader.h: Added new section describing the #include macros. the Type 2 glyph charstring (used by conversion programs). * docs/docmaker.py: Added cross-references generation as well as seac emulation provided by the Type 2 endchar operator. * src/cid/cidafm.c, src/cid/cidafm.h: removed un-needed files, Added support for clipped direct rendering in the smooth renderer. * src/cff/t2objs.c (T2_Init_Face): For pure CFF fonts, set
