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.
