  * Softpipe surface functions.
- * Basically, create surface of a particular type, then plug in default
- * read/write_quad and get/put_tile() functions.
- * Note that these quad funcs assume the buffer/region is in a linear
- * layout with Y=0=top.
- * If we had swizzled/AOS buffers the read/write quad functions could be
- * simplified a lot....
