IE9 very slow when PIE used

Hi all,

At first, thanks a lot for this awesome module ! It's very elegant way to integrate PIE to drupal in my opinion.

On IE9, we have noticed horrible lags when using plenty of PIE selectors. After some investigation, we find this post on stackoverflow.

I have attach a patch with this issue. The patch add the css instruction "-pie-poll: false;" to all CSS3 PIE elements. It avoids the lags on IE9, when using PIE selectors.
