Summary Region is 432 bytes out of the box

Region is enormous! It has Vectors with a huge inline capacity. We should do something to make it smaller (and maybe especially optimize for the case where it ends up just being one rect).

Loading webkit.org makes large regions: Region 0x7fb766810f98: 208 segments, 84 spans yahoo.com: Region 0x7fb766811148: 442 segments, 76 spans These big regions are from Page::addRelevantRepaintedObject(). Many regions are small, however.

Is it possible to make it so that we can specify the inline size on the Region? Then we can make the relevant repainted object ones big and default to small?

I think what we really want for tracking repaint rects is some sort of non-exact region that tries to stay simple...

(In reply to comment #4) > I think what we really want for tracking repaint rects is some sort of non-exact region that tries to stay simple... That is probably true.
