- * A class to parse color values
- *
- * NOTE: modified by danvk. I removed the "getHelpXML" function to reduce the
- * file size, added "use strict" and a few "var" declarations where needed.
- *
- * Modifications by adilh:
- * Original "RGBColor" function name collides with:
- * http://www.w3.org/TR/DOM-Level-2-Style/css.html#CSS-RGBColor
- * so renamed to "RGBColorParser"
- *

- * @license Use it if you like it
