Render glyphs in foreground?

I was just thinking, mips2java is getting pretty fast. I can render a glyph
under hotspot in 3-5ms (slightly less under gcj). Maybe we should do away
with background glyph rendering and just do it all in the foreground? It
would make things a whole lot simpler (in the core and widgets).

On slow machines we could end up blocking the foreground thread for a second
or two. This is a one time thing though so it might not be a problem.
