Please describe the problem:
Before the addition of the damage extension code, ximagesrc copied the entire
screen out per frame, which was bad.  Now, with the damage code we copy out the
area of the screen that was damaged for each set of damage that occurs.  If the
screen is changing faster than the framerate, this will probably be worse than
pre-damage.  So, instead I changed it so that only use the union of all the
damage that happens between frames.  Patch to follow.

Steps to reproduce:

Does this happen every time?
