We need to figure out how to apply a transform to a widget's drawing.

I have added a reduced testcase that visualizes the most significant bug with iframes. It seems that if you do scale(0.5) on the outer container of the iframe, the iframe will inherit the scale value, scaling it to 0.5 of 0.5 (but strangely ignoring scrollbars, or just not showing them). Weird enough, this does work well in Chrome. Probably must have worked before in a WebKit version?

Workaround for this issue is to set the following CSS property on the containing element i.e. the body tag in the testcase: -webkit-transform-style:preserve-3d;
