Could we get a gl_context for these as well ? It might be useful since
if we want allocate or destroy (more likely) gallium objects we'll need
a context.
NewQueryObject has a context argument as well.

I could save the context from the Begin/End calls, but if there's no
reason not to pass a context to New/Delete, having it as arg would be
preferable.
