I just want to note that FlashCanvas has some serious limitations with `drawImage` operations that made it unusable in a project I worked on. See notes here: https://groups.google.com/group/flashcanvas/browse_thread/thread/a16eea741872b085/d0e66cc44b1441c6

Awhile back, I created a demo to test performance in IE: http://bentruyman.com/lab/canvas/dyo/

In my tests, FlashCanvas inconsistently rendered several images layered which sometimes left the canvas empty, partially rendered, or caused flickering.

While it's a pretty decent polyfill, it does have some quirks and catches (even outside of `drawImage`).
