Skip occluded tiles during rasterization.
This causes the LayerRasterTileIterator to skip occluded tiles by tracking the occlusion for each layer and then determining whether each tile is occluded or not. The occlusion information is stored on the tile. Another CL will be created to store the occlusion information on the TilePriority instead so that the same tile can have different occlusion on each tree. This patch depends on https://codereview.chromium.org/246673005 or similar changes that cause the raster iterator to be used.
