I was running some experiments and I noticed that some AGL and GLX 
programs generate CGL calls which are not documented.  Have you run 
into these problems?  I always assumed one of the undocumented calls 
linked the window with the context..is this what you're doing in the 
render spu??

How functional is your patch have you tested with AGL, GLX and Cocoa 
apps?  If your patch isn't fully functional yet maybe we should merge 
both of our patches since mine appears to be fully functional for GLX 
apps.  Take a look at what I've done and let's see if we can add a 
compilation option where we can compile with only GLX support and this 
is fully functional for now or we can compile CGL which will be 
experimental till you get your stuff up and running. This will get 
people up and running on Darwin fast.

On the other hand if you feel CGL is complete enough to support CGL, 
AGL, and GLX apps - then maybe we should ignore my patch completely :-)

As for creating a patch -- I usually track chromium on my own cvs 
server and run a cvs rdiff to generate my patches.
