The plan right now is to contribute this in two patches:
1. Instead of using a ShareableBitmap for each update, use a big ShareableBitmap that's divided to smaller updates, like an atlas.
2. Create a GraphicsSurface class that supports software/hardware rendering and fast (DMA) copying, to be implemented differently for different platforms - first implementation with IOSurfaces for Mac.
