======================================================================================================

 This script was tested with the following systems and browsers:

 - Windows: IE, Opera, Firefox, Chrome

 If you use another browser or system, this script may not work for you - sorry.

------------------------------------------------------------------------------------------------------

 USAGE:

 Use the toolTip-function with mouse-over and mouse-out events (see examples below).

 - To show a tooltip, use this syntax: toolTip(text, size, opacity, padding, border)
   o text: HTML content
   o size: width in pixels or "width:height", example: "270:100"
   o opacity: 1 - 100
   o padding: pixels
   o border: CSS rule, example: "1px solid red"
   Note: all arguments except for text are optional. Opacity is not supported by all browsers.

 - To hide a tooltip, use this syntax: toolTip()

------------------------------------------------------------------------------------------------------

 EXAMPLES:

 <span onMouseOver="toolTip('Just a <b>test</b>', 150)" onMouseOut="toolTip()">some text here</span>
 <a href="image.jpg" onMouseOver="toolTip('<img src=thumb.jpg>', '320:240', 100, 0, '')" onMouseOut="toolTip()">my image</a>
