Currently there is no standards for when CALayer should be repainted. The current suggestion is to use a 50 FPS timer. The Flash Beta is also currently sending InvalidateRect that have been used experimentally reduce expensive composition operations. If hardware backend is ready we can use DisplayLink to drive the refresh.

We need to find an acceptable strategy before we can ship the Core Animation drawing model.

Resolving this issue should block any beta as this is an important part of our Mac OS X plugin strategy.

This patch add supports for the 'NPDrawingModelInvalidatingCoreAnimation' drawing model described here:
https://wiki.mozilla.org/NPAPI:InvalidatingCoreAnimation

We will need a follow-up patch to remove CoreAnimation (or whitelist) once we are ready.

I'm not marking this as fixed yet because we still need the follow-up work noted above.
Could we please file new bugs for followups here? And nominate them appropriately for 1.9.3 etc?

Sure, I'll fill a follow bug tomorrow to implement an optimization Josh told me we could make.
