+    #some reason the OpenGL site suggests using the latest glxext.h, 
+    #and glxext.h defines all GLX extensions, which doesn't seem right for

+    #which conflicts with: the ABI registry from what I saw on opengl.org. 
+    #By disabling some of the #defines in glxext.h we break some software,
+    #and by enabling them without the symbols we break others (in Mesa).
+    #I think a lot of OpenGL-based programs have issues one way or another.
+    #It seems that even Mesa developers are confused on this issue, because
