Subject : cc: Separate raster and decode prepaint regions.
Author  : vmpstr
Commit description:
  
This patch separates raster and decode distances to be
independent of each other. Specifically, any tile in prepaint
that is further than 1000 screen space pixels from the
viewport will not be rasterized. Instead, we will pull out
the images on those tiles and predecode those instead.
