Differentiate between blocks that are visible and those that probably

aren't (we can't truly know if a block is visible until we resolve it
because objects of arbitrary height can overlap the view bounds even if
the block's footprint does not); resolve the definitely visible ones first
and go ahead and start drawing once the known visible blocks are ready.
This cuts the time spent on the "blue screen" by about 75%.
