Description Adam Roben (:aroben) 2011-04-07 09:54:10 PDT 
In WebKit2 on Windows, accelerated compositing happens on the main thread. This means that pauses on the main thread can result in stuttering animation (e.g., bug 57956).

We should move compositing off the main thread so that it isn't affected by the business of the main thread. This is how accelerated compositing works in WebKit1, and on Mac.
