Lucas Scharenbroich 95058fb969 Checkpoint for sprite rewrite
All of the sprite rendering has been deferred down to the level of
the tile drawing. Sprites are no longer drawn/erased, but instead
a sprite sheet is generated in AddSprite and referenced by the
renderer.

Because there is no longer a single off-screen buffer that holds
a copy of all the rendered sprites, the TileStore size must be
expanded to hold a reference to the sprite data address fo each
tile.  This increase in data structure size require the TileStore
to be put into its own bank and appropriate code restructuring.

The benefits to the rewrite are significant:

  1. Sprites are never drawn/erased off-screen.  They are only
     ever drawn directly to the screen or play field.
  2. The concept of "damaged" sprites is gone.  Every dirty tile
     automatically renders just to portion of a sprite that it
     intersects.

These two properties result in a substantial increase in throughput.
