We use the normal font backend stuff, there is a new one = for cairo (ftcrfont.c), based on the Freetype backend (ftfont.c). >=20 > If the latter, then one problem we'd need to figure out is what to do > with bidirectional display, since AFAIR Pango does its own reordering. >=20 > Another interesting issue is whether we want to use Cairo on Windows > as well, and eventually drop the w32-specific display back-end. You have to separate the event and system interaction from the rendering = in w32, but also in the X backend so to have a pure resuable cairo = rendering code base. Right now its all kind of mixed in. Jan D.
