Why this wasn't allowed is beyond me.
Because that resulted in allot better performance.
It doesn't make much sense to let the driver blit the content of a
texture into a tilled version and make a single draw and then throw away
that tilled version before the next draw.
So either leave the test there or move it into r600_texture_create, but
don't remove it altogether.
Christian.
Eventually I'd like to make every format blittable, so that the function
can go away.
