Make the test sprite movement a bit more interesting
...
This results in trails being left on-screen and crashed after
a period of time. The emulator shows writes going to the
bank 01 I/O space ($01/$Cxxx) and there are occational garbage
words written to the screen.

Tile rendering reorganization
...
This significantly simplifies the dispatch process by creating a
proper backing store for the tiles. Most values that were
calcualted on the fly are now stored as constants in the tile
store.
Also, all tile updated are run through the dirty tile list which
solved a checken-and-egg problem of which order to do sprites vs
new tiles and affords a lot of optimizations since tile rendering
is deferred and each tile is only drawn at most once per frame.
