Author: Marek Olšák <[email protected]> Date: Thu Oct 22 19:46:07 2015 +0200 st/mesa: don't load state parameters if there are none Out of 7063 shaders from my shader-db: - 6564 (93%) shaders don't have any state parameters. - 347 (5%) shaders have 1 state parameter for WPOS lowering. - The remaining 2% have more state parameters, usually matrices.
