* docs/*: serious rewriting of the documentation * include/freetype/internal/ftobjs.h, src/base/ftobjs.c, src/bdf/bdfdrivr.c, src/pcf/pcfdriver.c, src/pfr/pfrsbit.c, src/sfnt/ttsbit.c, src/type42/t42objs.c, src/winfonts/winfnt.c: introduced three new functions to deal with glyph bitmaps within FT_GlyphSlot objects. these are: ft_glyphslot_free_bitmap ft_glyphslot_alloc_bitmap ft_glyphslot_set_bitmap these are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP flag manually. the font drivers have been modified to use them as well. * src/cache/ftlru.c: fixed an invalid assertion check

How to enable the TrueType native hinter if you need it
--------------------------------------------------------
The TrueType bytecode interpreter is disabled in all public
releases of the FreeType packages for patents reasons (see
http://www.freetype.org/patents.html for more details).
However, many Linux distributions do enable the interpreter in the
FreeType packages (DEB/RPM/etc.) they produce for their platforms.
If you are using TrueType fonts on your system, you most probably
want to enable it manually by doing the following:
- open the file "include/freetype/config/ftoption.h"
- locate a line that says:
#undef TT_CONFIG_OPTION_BYTECODE_INTERPRETER
- change it to:
#define TT_CONFIG_OPTION_BYTECODE_INTERPRETER
of course, this must be done _before_ compiling the library
