Great!

I tested my code using the git head + os mesa this morning and I am 
happy to report that it works just fine!!

I encountered a few issues though. The following symbols were missing 
from libOSMesa when built with ---disable-shared-glapi. I'm attaching 
the patch I used to solve it.

                  U glAreTexturesResidentEXT
                  U glDeleteTexturesEXT
                  U glGenTexturesEXT
                  U glGetColorTableEXT
                  U glGetColorTableParameterfvEXT
                  U glGetColorTableParameterivEXT
                  U glIsTextureEXT

I'm very excited about the recent improvements in os mesa!
