        Pre AA scrolling was in 140ns increments.

Sprites
-------

All sprites can now be displayed in either:

1) ECS default mode
2) 140 ns (this is not ECS mode!)
3) 70 ns
4) 35 ns

on display resolution. eg 35 ns sprites on a lores screen, or 140 ns
sprites on a superhires screen.

Sprites are either 16, 32, or 64 bits wide.

Sprites can be attatched in any mode (formerly could not attach sprites
in the ECS SHRES 35ns resolution mode).

Can use any bank of 16 colours from the 256 colour palette for the sprite
colours.

Key:

 ! needs 1x Bandwidth (old modes)
 @ needs 2x Bandwidth (normal CAS 32bit bus with or double CAS 16 bit bus width)
 $ needs 4x Bandwidth (double CAS 32bit bus width)
