[webkit-dev] Partial SVG repaint

SVG was designed to support this, it's just not been turned on yet.
It would be one little patch and a lot of little patches afterwards to
fix things that break. :)

You'd just add a checks in RenderSVGContainer and RenderPath to see if
the dirty rect intersected the repaintRectInLocalCoordinates.

I think that could add a bunch of under-painting bugs, but
theoretically if of stored bounding box calculations are correct, then
such a change should be fine.

I'm not sure I would suggest such a change as your first change to
WebKit though.  It could have lots of fallout. :)
