Went through my piled-up PyOpenGL email from the vacation and tried to address the various bugs and issues. Other than confirming a fix on hardware I don't have we should be pretty close to ready for a second beta. I regenerated the extensions based on the latest khronos api svn, so we should be pretty up-to-date, but I really need to get some GLES test cases to confirm that we do actually have basic GLES2 support working.
