Apple II Cycle-Counting Fireworks demo
	by Vince "Deater" Weaver
	vince@deater.net
	http://www.deater.net/weave/vmwprod/
	
Loosely based on a BASIC program by FozzTexx

Usage:
	BRUN FIREWORKS

	press any key to toggle sound and restart

This code uses cycle counting extensively.
This is how HGR and 40x96 LORES are mixed.

HPLOT0 was made cycle-invariant, which was a pain.
HGLIN (allowing HPLOT TO) was intended to be too, but I ran out of interest.
