Re-land: cc: Reduce picture cloning by creating at most one clone per raster thread.
This adds raster sequences to the TileManager. Raster tasks posted to
the same sequence are guaranteed to run in sequential order, which means
only one picture clone per sequence is required. We use the same number
of raster sequences as raster threads.
