caillon%returnzero.com 0f7366d6d0 Correcting our background painting code per the latest CSS specs. By default, backgrounds should be painted to the border 
area, and not the padding area as per the CSS 2 Errata, CSS2.1 and CSS3.  Also, implementing the CSS3 'background-clip'
and 'background-origin' properties (currently with -moz- prefixes) to control this behavior.
