Easier said than done... the reason I've been using freetype.GetStringGray
(oops, excuse me -- freetype.TFontManager.GetStringGray) is that it returns
TStringBitmaps, which I can use within my framework. It looks like the behavior
of XftDrawStringUtf8 is to draw something on the screen, whereas I need to
access the individual character glyphs and do the drawing later. hum.
Is there some secret, hidden documentation for fpc's freetype unit? (and so many
other units?) :P
