This seems redundant to pass along visible_tile.  You can get this information
from the tile itself?

Yes, using manfred's tile->required_to_draw() now instead.

 
   // Given an empty raster tile priority queue, this will build a priority queue
   // that will return tiles in order in which they should be rasterized.
