Mixed document invalidates *way* too much on canvas animation

See attached document.  Run it under quartz debug to see it invalidating the entire screen on each frame.

the web archive also seems to take up a larger page size than the original did.  Meaning there is now a scroll bar.  Odd.

gah, the webarchive does not appear to work for me :-/

That said, if this is one of the CAKE demos i believe the clear the entire canvas at the beginning of each frame in most of their demos -- thus ensuring we can't reduce the repaint region.

So I am tempted to close this as works correctly -- that's a blind recommendation though, i'd like an url that i could actually test :D

Probably was a cake demo.  Probably tries to load external scripts via xhr
