*
* This is a problem if this is the first buffer coming in,

* yet (likely because the MakeCurrent() command is in the
* buffer itself).
*
* At best, in this case, the functions are no-ops, and
* are essentially ignored by the SPU. In the typical
* case, things aren't too bad; if the SPU just calls
* crState*() functions to update local state, everything
* will work just fine.
*
* In the worst (but unusual) case where a nontrivial
* SPU is at the head of a gl stub's SPU chain (say,
* in a multiple-tiered "tilesort" arrangement, as
* seen in the "multitilesort.conf" configuration), the
* SPU may rely on state set during the MakeCurrent() that
* may not be present yet, because no MakeCurrent() has
* yet been dispatched.
*
* This headache will have to be revisited in the future;
* for now, SPUs that could head a gl stub's SPU chain
* will have to detect the case that their functions are
* being called outside of a MakeCurrent(), and will have
* to handle the situation gracefully. (This is currently
