Accelerated Compositing: screen garbage when scrolling

Re-work the way the compositor handles invalidations, scrolling 
and repaint requests. Previously, compositor piggy-backed on the 
software rendering path for handling of these events. This CL, 
paired with webkit bug 45092 allows the compositor to track and 
manage invalidations, scrolling and repainting independently, 
allowing us to fix a number of accelerated rendering bugs stemming 
from interaction with the software renderer.
