Details
The view manager should be modified to accumulate/coalesce paint requests for a set of views that share a common widget, and a timer should be used to throttle the frame rate at which repaints occur. At the very least, this mechanism should be used to limit the number of repaint requests that go to nsIWidget::Invalidate(), but even more ambitiously, when the timer fires, the updates could be processed without a round trip through the OS.

This is partially implemented now. Still need to look into timer based
throttling.

This bug is marked "future" because it is not critical for RTM (Release To
Manufacturing). If anyone believes it is critical, please explain why in
this bug.

The paint events are currently being coalesced. Painting is already being
batched and processed by Disable/Enable Refresh calls made to the viewmanager
from layout and the EventStateManager so there is no need for timer based
throttling. Marking this bug Fixed.
