This patch keeps the state of used layers and updates it in register and unregister tile. This eliminates the need for CleanUpImageDecodeTasks. This also provides a fix to the memory limits in the perftest, so by comparison the performance should drop significantly. However, this is only because the perftests are now properly testing the full ManageTiles code path. The patch to remove CleanUpImageDecodeTasks actually improves performance by about 15%.
