Sprites 

The number of sprites available will depend on the type of display and the fetchmode
settings Most AGA modes will require the display to be shrunk horizontally for 8
sprites to be displayed. Currently this can only be acheived using the DisplayAdjust
command, certain examples of this can be found on the Blitz examples disk.

AGA hardware allows the programmer to display sprites in lores, hires or superhires.
The higher resolutions allow graphics dithering by the artist, essential if 3
coloured sprites are in use. Larger sprites are also available using the SpriteMode
command. Dithered large, super hi-res sprites can be created to look better than
lower resolution 16 color sprites using such tools as ADPro.

Note that it is unrealistic to display more than 4 bitplanes and have more than 3
sprite channels available, the adjust required results in a very narrow display
indeed.
