Exactly. I have a patch (at work) which optimizes damage recording quite
a bit (specifically, it avoids excessive growing of the damage region
when two rectangles are merged). As a side effect, it makes sure that
the final list of damage rectangles is non-overlapping.
I will post it on Monday when I've picked it up from that image at work.
Cheers,
Hans-Martin
