When two sprites occupy the same tile, their screen y coordinate is used

instead of their fine coordinates. It achieves the same effect and
alleviates the need to track fine coordinates in the MisoCharacterSprite.

Additionally, IsoSceneView and friends were modified to allow any sprites
to wander their crooked realms, MisoCharacterSprite instances are simply
more efficient because they maintain cached copies of their tile
coordinates whereas other sprites must have their tile location computed
from their screen location whenever they are to be repainted.

At some point in the future, the tile coordinate tracking facilities of
MisoCharacterSprite should be accessed through an interface so that other
spritely entities can cache their tile coordinates if they so desire.
