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.

Optimize the simple mixed BG0/BG1 handler
...
There is enough room in the 32-byte exception handler to inline the
9-byte epilogue when generating the code sequence for mixed BG1/BG0
rendering.
This code sequence is generated once and run for as many frames as the
word appear on screen, so saving an uncondition branch (3 cycles) at the
cost of 60 cycles is probably worth it.
