/* This looks like a lot of work at the moment - we're keeping a
* duplicate copy of the state up-to-date.
*
* This can change in two ways:
* - With constant state objects we would only need to save a pointer,
* not the whole object.
* - By adding a callback in the state tracker to re-emit state. The
* state tracker knows the current state already and can re-emit it
* without additional complexity.
*
* This works as a proof-of-concept, but a final version will have
* lower overheads.
*/
/* Bring the software pipe uptodate with current state.
*
* With constant state objects we would probably just send all state
* to both rasterizers all the time???
