Mouse cursor

[thejpster]

We might have enough CPU time to paint a single sprite on the screen. Basically if line >= min and <= max, then write a handful of 16 bit RGB words into the scan line we just drew.

The Archimedes had a single sprite which it used for a mouse cursor.

If we want to burn some RAM, we could do a single sprite per scan-line, with a display list per scanline stating which words to write and with what. Would cost 480 pointers (one per line) plus 16 bits per sprite pixel, plus four bytes per active line for the X position and width. Would cost about 3K of RAM.
