* Headers/cairo/CairoFaceInfo.h (-fontFace): Use
* Source/cairo/CairoGState.m (-DPSImage::::::::):
For the ARGB32 case sort the colour fields in the bitmap correctly.
2005-08-20 Fred Kiefer <FredKiefer@gmx.de>
* Source/cairo/CairoFaceInfo.m (-fontFace): Use
_cairo_toy_font_face_create, as Cairo did rename this function.
* Headers/cairo/CairoFontInfo.h (_cairo_glyph_for_NSGlyph): Use
* Source/cairo/CairoFontInfo.m (_cairo_glyph_for_NSGlyph): Use
Cairo function _cairo_scaled_font_text_to_glyphs to convert to glyphs.
