Chris Jones fc6d547510 Bug 750977: Implement glue code for asynchronous panning/zooming. r=jlebar,roc,vingtetun
This is a rollup of three separate patches
 - Add nsIDocShell.asyncPanZoomEnabled. r=jlebar
 - Have BrowserElementChild service repaint requests and handle fallback synchronous scrolling (for now). r=jlebar,vingtetun
 - Glue async pan/zoom logic up between compositing, event dispatch, and repaint requests. r=roc
