Hi Phil: My two objections to the current plfreetype approach are its clunky selection of fonts (by file name rather than by generic sans, serif, etc., font type search for the best system font with the desired generic characteristic to render a single unicode glyph) and its inability to deal with complex text layout. However, it sounds like those two objections are answered by the concept you describe above if working indirectly through an improved plfreetype is the approach Jim and Aaron decide to take with the wingcc upgrade. And an improved plfreetype with the above objections answered would certainly give a huge boost to the gd device driver (also dependent on plfreetype) back from its current course toward complete retirement.
