Question about using xorg-gtest

[Ian Romanick]

A long time ago when I first implemented GLX_ARB_create_context, I 
implemented some unit tests using gtest.  My tests provided some 
scaffolding functions and poked directly at code that I added for the 
extension.  I used this to verify certain aspects of the protocol 
generation, etc.  I wired these up (in my build) to run with 'make check'.

I'd like to add these somewhere, and I'd like to add more tests in a 
similar vein.  Does anyone have any suggestions for doing that?  This 
seems different from the current gtest usage.
