AFAIK, all discussed ways to restore windowed OpenGL functionality are more or 
less evil hacks. So, maybe Wine should partially restore the old (broken) WM 
code for OpenGL viewports? This would be the most streight and performant way, 
and if Wine only creates additional X windows for OpenGL viewports, the bugs 
fixed by the WM rewrite shouldn't reappear, anyway...?
