From 26c6640835936a77d87030ce8e90f9b9f5be783e Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Mon, 15 Jul 2019 14:44:48 +0200 Subject: gallium/u_blitter: set a more sane viewport-state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This actually corresponds to legal GL depth-ranges, because depth-clear values are always in the 0..1 range in OpenGL.
