#3981 IE 6 & 7 reports incorrect CSS opacity values in jQuery 1.3.1


I'd like to give this ticket (http://dev.jquery.com/ticket/3981) a
bump, after stumbling about the same problem while trying to animate
an element with fadeIn, which has an opacity value set in a
stylesheet.
The attached patch fixes the problem in my case. It duplicates parts
of whats already there for parsing the filter value, but otherwise it
looks fine.
Any reason not to commit it to get it included in 1.3.3?
