Excellent.

In fact I wasn't talking about sharing contexts between windows, but  
sharing resources -- that is textures, display lists, vertex buffers  
and shaders -- between contexts. Context creation routines in agl and  
glx (and wgl ?) allow you to specify another context to share  
resources with.

A context per window, as does glut, would be fine with me (and maybe  
simpler to implement) as long as I can share resources between them.  
Especially interesting is sharing a windowed context with a  
fullscreen one to allow seamless toggle between fullscreen and  
windowed mode.

Best,

Daniel
