  GrantSkinner's great job, and look at Zoë library, "It’s also worth mentioning here that Flash Pro CS6 will include direct support for exporting sprite sheets for EaselJS, offering a more integrated workflow than Zoë can provide."

this is a case:

  In a very large-size Movieclip (as a game 'map', roughly 4000(width) * 2000(height)), set this movieclip's property 'cacheAsBitmap' to true, and this mc has dozen children, when you start drag this mc, you could obviously feel 'mousemove' is not smooth, Even if you register the mousemove listener and handle 'updateAfterEvent' method. drag mc is still not smooth. （and worse the fps is slower).

 so read adobe's API documentation, found the 'cacheAsBitmap' property has some pay attention points...
 "The cacheAsBitmap property is best used with movie clips that have mostly static content and that do not scale and rotate frequently. " 

 so I think this maybe the reason why above example's mc drag is not smooth, because internal children is change it's propery(like, 'rotation' "x", "y") will handle entire root mc to recreate the bitmap cache. and the mouseEvent's method
'updateAfterEvent' will enforce flashplayer to redraw immediately in every mouseMove operation.

	if(extent > 0){
		offset = values >>> (32 - extent);
