Currently on the b2g homescreen when we draw the next page we have to sync decode the image. This takes add about 30ms to the frame which will cause missed frames in panning. Ideally before we render that tab we would kick it off to decode off the main thread. This should happen before the pre-rendering of active layers (which are 32 pixels away).
