Author: Gert Wollny <[email protected]> Date: Wed Apr 24 09:53:56 2019 +0200 softpipe: Add support for TGSI_OPCODE_INTERP_OFFSET Since for this opcode the offsets are given manually the function should actually also work for non-zero offsets, but the related piglits only ever test with offset 0. Accordingly the patch satisfies "fs-interpolateatoffset-*".
