Things To Do
			    (in no particular order)


* Determine blob sizes passed to glXxxPointer functions.

  Potentially using tricks such as:

  * http://stackoverflow.com/questions/1281686/determine-size-of-dynamically-allocated-memory-in-c

* Drop GLEW dependency -- the supported extension subset is different from what
  we want, and it is trivial to code generate the wrappers

* Trace multiple threads
  * GetCurrentThreadId()
  * pthread_self()

* Trace TSCs

* Retrace multiple threads (which will imply abandoning GLUT)

* Provide a readline-like interactive mode to gltrace
