Subject : cc: Move prepaint region calculations to the tiling set.
Author  : vmpstr
Commit description:
  
This patch moves prepaint region calculations from the tiling to the
tiling set. This ensures that new tilings get proper skewport
information. It also allows us to retrieve prepaint regions
independently of tilings present, which is useful for iterating images.
