Dan regarding your comment that AJ won't accept a patch to readd child windows.
We have talked with him on IRC and he is not against this. The patch only adds
child windows for opengl not for other cases. If the patch fixes more issues
than it creates AJ would be willing to accept. But we need a lot of proof.

The opengl code is becoming very dirty due to the glscissor and other hacks.
Further child window support would not only help fixing windowed opengl
rendering.  Right now wine is limited to a single pixelformat which poses issues
for opengl32/wined3d. For a part it could result in lower performance and second
due to it things like multisampling in opengl programs can't be supported (and
more).
