I don't agree with that, it's the GTK that's not adapted to remote
framebuffers - it could be much snappier on the glamo, but it could be
much snappier on the GTA01 too if it did a little caching (on glamo
side or locally) instead of redrawing stuff constantly - just in case
something has been resized.  Note that I don't dislike GTK+.

I've been prompted to look at it when OM started to simplify themes by
removing bitmaps - the bitmaps and gradients should really make no
difference in UI speed, but they do.

On the other hand I don't agree with Mickey that we shouldn't modify
GTK+.  It definitely needs to be taught to cache graphics or it won't
be very successful on mobiles.
