QOffscreenSurface may create an invisible QWindow. In our case that's the<br />
case, for each offscreen surface a native window is created. This may<br />
lead to some funky results related to window decorations, see bug 407612.</p>
<p>There are several ways to implement offscreen surfaces - either use pbuffers<br />
or utilize a surfaceless context extension. For the sake of simplicity<br />
this change sticks with pbuffers, but it's a good idea to support both<br />
methods.</p>
