-// ALGORITHM NOTES
-//
-// We attempt to maintain a scroll rect in the presence of invalidations that
-// are contained within the scroll rect.  If an invalidation crosses a scroll
-// rect, then we just treat the scroll rect as an invalidation rect.
-//
-// For invalidations performed prior to scrolling and contained within the
-// scroll rect, we offset the invalidation rects to account for the fact that
-// the consumer will perform scrolling before painting.
-//
-// We only support scrolling along one axis at a time.  A diagonal scroll will
-// therefore be treated as an invalidation.
