BTW, that problem you mentioned can be solved like this: application and 
windows has their own threads. It could be possible to use the window 
thread just for message handling, with no GL calls. Then acquire the 
context of that window in the application thread and make it handle all 
rendering (first the world and then tell the contained widgets to render 
themselves) and game mechanics.
