What would be a good place for this in the blorp code? I am guessing the only time that blorp would trigger an astc read is in blitting… what would you suggest for keeping it inside of blorp? The blorp_context struct is part of blorp not i965… to keep it in blorp would mean it needs to be passed down along the function calls somehow …

Let's keep all of the code for detecting whether or not BLORP needs and implementing it together in BLORP. We can just as easily detect ASTC5x5 there as here.
