Hack to work around rendering issue

Silverlight 5.x appears to use Direct3D for rendering, and for some reason the
full-page windows no longer render on top of the browser window.  This is
likely not a regression per se, but since commit
514eb695846b45c89c0fc0d56653d187f1840eec the Silverlight 5.x window can no
longer be seen if it's a full-page application.  Examples of this are
applications like Netflix.

winex11: Store the rectangle of the GL drawable and use it when updating
the window size.

The attached hack can be used to somewhat work around the issue (the window can
still be occluded, but mousing over elements will bring things back).
