* src/base/ftobjs.c (FT_Load_Glyph): Fix boundary check for
`glyph_index'.
2003-04-25: Graham Asher <graham.asher@btinternet.com>
Added the optional unpatented hinting system for TrueType. It
allows typefaces which need hinting to produce correct glyph forms
allows typefaces which need hinting to produce correct glyph forms
(e.g., Chinese typefaces from Dynalab) to work acceptably without
infringing Apple patents. This system is compiled only if
TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in
ftoption.h.
* include/freetype/ttunpat.h: added header file ttunpat.h defining
FT_PARAM_TAG_UNPATENTED_HINTING.
