Description Oliver Hunt 2008-04-28 02:59:19 PDT 
A canvas can no long draw itself into its own buffer, this is used for a number of "accumulator"-esque graphical effects and so represents a significant regression

My guess is this is due to http://trac.webkit.org/changeset/31961, although i cannot be sure
