$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');
		};

// Revised May 7 99 to add is.nav5up and is.ie5up (see below). (see below).
// Revised June 11 99 to add additional props, checks
// Revised June 23 99 added screen props - gecko m6 doesn't support yet - abk
//                    converted to var is_ from is object to work everywhere
// 990624 - added cookie forms links frames checks - abk
// 001031 - ie4 mod 5.0 -> 5. (ie5.5 mididentified - abk)
//          is_ie4 mod tp work with ie6+ - abk
// 001120 - ns6 released, document.layers false, put back in
//        - is_nav6 test added - abk
// 001121 - ns6+ added, used document.getElementById, better test, dom-compl
// 010117 - actual version for ie3-5.5 by Michel Plungjan
// 010118 - actual version for ns6 by Michel Plungjan
// 010217 - netscape 6/mz 6 ie5.5 onload defer bug docs - abk
// 011107 - added is_ie6 and is_ie6up variables - dmr
// 020128 - added link to netscape's sniffer, on which this is based - abk
//          updated sniffer for aol4-6, ie5mac = js1.4, TVNavigator, AOLTV,
//          hotjava
// 020131 - cleaned up links, added more links to example object detection
// 020131 - a couple small problems with Opera detection. First, when Opera
//          is set to be compatible with other browsers it will contain their
//          information in the userAgent strings. Thus, to be sure we have

// 020214 - Added link for Opera/JS compatibility; added improvements for

//          Hill, Les.Hill@getronics.com, for the suggestion).
// 020531 - Added N6/7 and moz identifiers. 
// 020605 - Added mozilla guessing, Netscape 7 identification, and cleaner
