No description provided.

Instead of allocating a tile surface from the texture cache during
the tile post_update method, this is now deferred until the
take_context method of picture.

This will allow a simple CPU occlusion culling pass to run after
all the tile cache dependency updates (when the visible tiles and
rects are know), but before the surfaces are allocated. In this way,
we will be able to skip allocating, rasterizing and compositing
any tiles that are eliminated by the occlusion culling test.
