Do you *really* read to redraw the entire screen? If your user taps near
the upper-right corner, is the whole screen changed or an area localized
around the tap?
If the latter, I suggest looking at dirty rectangles approach. Keep a list
of what rectangles need to be updated and blit only those. Of course, this
has to be balanced by the overhead of managing a list and keeping the number
of rectangles down, but if very little changes from frame to frame, you
could probably save a decent amount of time.
