Author: Kenneth Graunke <[email protected]> Date: Thu Aug 17 00:17:05 2017 -0700 isl: Add a null surface fill function. ISL already offers functions to fill out most kinds of SURFACE_STATE, so why not handle null surfaces too? Null surfaces are simple, so we can just take the dimensions, rather than an entirte fill structure.
