$Id: pint_rolloverDEBUG.js,v 1.5 2003/07/03 17:01:44 cducker Exp $

Creator: J. Brock

Description:
	This rollover code is supposed to be 
		1. flexible, to accomodate all possible rollover activity
		2. compatible, should work on anything better than IE4, Netscape 4
		3. easy, so that all the rollover information can be inserted into the img tag in a simple way
		4. robust, so that errors, typos, bad DOM support make it degrade gracefully

Dependancies:
	pint_initcleanup.js

Usage:
	In pint_initcleanup.js:
	function init()
		{
		PINT_RORolloverInit('img1', 'img1', 'img1on.png');
		PINT_RORolloverInit('img2', 'img2', 'img2on.png', 'img1', 'img1on.png');
		};
