cc: Move activation check into TileManager
Currently "AreVisibleResourcesReady" requires a tree and tiling walk to
calculate, which means that it's not going to be cheap enough to call
repeatedly during a frame. This is one step towards making activation happen
sooner.
This patch only changes "AreVisibleResourcesReady" into
"MarkVisibleResourcesAsRequired", marking individual tiles as being required
for activation. The TileManager recalculates the set of required tiles when
assigning gpu memory, so that "required" tiles that don't get memory won't be
considered. This lets it very cheaply determine how many outstanding tiles
are needed for the frame.
