But Pango already has a Win32 back end.
Also I don't understand 100% how a FreeType back end
is different to a TrueType back end. Is FreeType not
compatible with TrueType on the level I thought?
Having both TrueType and FreeType on an OS just sounds

Myself included but not too many church secretaries
are going to edit their FreeType makefile and rebuild
to get AbiWord to antialias like all their other
software already does automatically.

So it's equivalent to using Xft?

So are you suggesting using pangoft instead of
pangowin32 even on Win32?
