- 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).

Random, instead it relies on a duplicatable hashing method.

code to log when we're not painting for lack of blocks and when we restore
painting so that we can further debug the proverbial blue screen situation.

after we've started displaying.

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%.

we do allow derived classes to dictate whether or not unresolved tiles are
passable. Additionally, we sanity check the number of nodes searched when
computing paths.

around and resolving blocks.

to be resolved.

traversable so that if a sprite claims to have relocated somewhere outside
your resolved scene bounds, we'll just bee line them to their new
location. Since the user can never click outside their resolved view
bounds, we won't ever compute an invalid path for them. Joy.

that are needed to repaint the visible view first and allow repaint as
soon as those blocks are resolved.
