I think this would be a good thing to do, but I was more thinking about
making a conformance test to sanity check that mixing Cogl and GLES2
works. Eg, it could render some stuff with GLES2, then with Cogl and
then with GLES2 again to verify that the code to bind the context works
correctly.

I guess running a full GLES2 conformance test would be more interesting
if we change from creating a separate context to making it share Cogl's
context because then Cogl will be doing a lot more stuff for each GL
call. Otherwise for now it would mostly just be testing Mesa.
