Color glyph framework and rendering (2/3).
* include/freetype/freetype.h (FT_GlyphSlotRec): Rename reserved
pointer `other' into `color'.
* include/freetype/ftglyph.h (FT_OutlineGlyphRec): Add new field
`color'. Technically this breaks binary compatibility but this is
highly unlikely.
* src/base/ftglyph.c (ft_outline_glyph_{init,done,copy,prepare}):
Handle color and copy it between FT_Glyph and FT_GlyphSlot.
* src/base/ftobjs.c (ft_glyphslot_clear): s/other/color/.
* src/type42/t42objs.c (t42_glyphslot_clear): s/other/color/.
