 * 3/11/2001
 * 
// dhtml scrolling panel featuring scrolling in any
// direction, smooth frame-dropping animation, and a
// few other goodies.
//
// 3/25/2001
// added scrolling in any direction and initTop, initLeft
// constructor parameters - with only 1k...
//
// 3/30/2001
// fixed bug that occured when if you called scrollTo( )
// and the new position was the same as the current
// position. that was stupid.
//
// 4/02/2001
// small bug fix - on some browsers, on slow connections
// the script would not run at all. to be sure the doc
// is done loading before .load() is called, the author
// must now call the .load() method in the onload handler
// for the page.
//
// 8/22/2001
// if you tried to scroll before page was loaded it threw
// an error. this should be fixed now.
