- Tiles are initialized after being constructed which makes life simpler
for custom tiles which no longer have to have their own constructor that
passes Tile's stuff down to it.
- Tiles are no longer LRU cached (because we blow through that cache
instantly on all but the smallest of scenes), and are now tracked by
weak references so that we guarantee that only one instance of a tile is
ever in memory.
- Added code to track and report memory usage of weak cached tiles as well
as "stray" tiles which are created through other means than asking a
TileSet for a tile (fringe tiles being the most prolific example).

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%.
