cc: Add pending tree for impl-side painting
Do tree synchronization to pending tree. Inform scheduler when there is a pending tree so that vsync can continue to be scheduled.
Right now everything is hooked through redraw, so canDraw is true when there is a pending tree, prepareToDraw is the one that checks for tree swap, and TileManager::DidFinishTileInitialization ends up calling setNeedsRedraw. I'm not sure this is ideal, but it's a start.
