From 171e633294baa29a2dfcf889764b6c7409cdc1ff Mon Sep 17 00:00:00 2001 From: Jordan Justen Date: Tue, 9 Jul 2013 14:56:38 -0700 Subject: [PATCH] gen7 depth surface: calculate more specific surface type This will be used in 3DSTATE_DEPTH_BUFFER in a later patch. Note: Cube maps are treated as 2D arrays with 6 times as many array elements as the cube map array would have.
