[Mesa-dev] [PATCH 1/6] tgsi: add TXQ support.

How would the TXQ instruction be implemented for a hardware driver?

Is there really a HW GPU instruction that returns the size of a texture?

Otherwise, this seems like something we could implement in the state 
tracker by putting the texture size into a constant buffer slot.  Then 
we'd have it for all drivers.
