Coalesce damage rects that share an edge.
This fixes the Bloat HTTP page cycler regression, and allows me to remove the
hack I checked in to disable multiple-paints due to an observed DHTML page
cycler regression.
I added a new histogram, RW_IntermediatePaintRectCount, that would have shown
the problem clearly had it been there before.
I included some cleanup in PaintAggregator:
1- rename "r" to "existing_rect" for clarity
2- check for contained (i.e., redundant) invalidates up front
I also changed the opacity of the paint rects used when --show-paint-rects is
specified. I find myself dogfooding with this command line option enabled, and
I want it to be a little less annoying but still just as useful.
