Another reason I did not implement dirty region repaint optimization
that I forgot to mention:

(3) Dirty region repaint handling does not help at all when most of the
screen is being updated on each frame.  Since I expect the "fancy menu"
to become more and more full of eye-candy (that is the purpose, after
all!), the dirty region handling would only help for the most vanilla
of themes.  I have said I will add some animation and special
effects to GRUB.  Things that I think would be cool (and cool => more
people drawn to use GRUB) include a fade-in/fade-out when GRUB
starts/executes an entry, a fully animated background of some sort (of
the type that many xscreensavers use), etc.
