Well... do they not? If not, why should they affect getClientRects?

-moz-element currently uses the untransformed size as the size of the
background image for -moz-element, and draws the transformed element
into that box, clipping at the edges. Screenshot of a 500px by 500px
div using the 45-degree-rotated div from my other example as a repeating
-moz-element background.
Why would there be an issue with -webkit-canvas? -webkit-canvas
presumably just uses the canvas backing store as the background image;
since the canvas it uses isn't even shown on the page there are no
transforms involved.
