cc: Use simplified region for pending invalidation.
Our invalidation regions can get very large in terms of the number
of containing rects, so unioning two of these regions causes a crash
(out of memory) on certain heavy pages. Using a simplified region
helps both performance in terms of time and in terms of memory.
