frames: Support opacity in frame drawing

Browse Source 
There's still a bug here (frame opacity doesn't "kick in" until we
change the frame geometry), and the colors aren't correct (we're
painting on top of a white surface, not a 0-alpha surface), but we
at least remove some redraw issues that come when you're not always
obscuring the last paint.
