Enhance getComputedStyle() for MSIE about base2 HOT 6 CLOSED

I can convert colours and metrics (width, height etc) to rgb and px 
respectively for
MSIE6/7. What else need fixing?

Latest changes checked in. Will wait for furthe issues to be raised.

I'm a bit confused regarding the implementation of getComputedStyle() for IE.

In firefox, to get the style property of an element, you'd use:
  document.defaultView.getComputedStyle(element, "").getPropertyValue(styleName);
But that doesn't work in IE, getPropertyValue is undefined.

What works in both cases is:
  document.defaultView.getComputedStyle(element, "")['styleName'];

Shouldn't getPropertyValue be implemented?

> Shouldn't getPropertyValue be implemented?

It will be in the next release.

getPropertyValue() is now implemented.
