456744027d Inline all functions that are only called once
Eliminates the JSR/RTS overhead for the copy functions.  Combined
with the other streamlining, we save around 60 - 70 cycles per
bank, or a total savings of around 10,000 cycles per seconds when
running at full screen.

This doesn't really change the FPS, but just gives some cycles
back to the main application logic.
