From 02a89dc163898b02b7ad2867359c1ee7a7574c1f Mon Sep 17 00:00:00 2001 From: Axel Davy Date: Sat, 10 Jan 2015 15:11:30 +0100 Subject: st/nine: Implement fallback for D3DFMT_D24S8, D3DFMT_D24X8 and D3DFMT_INTZ Some drivers support PIPE_FORMAT_S8_UINT_Z24_UNORM, some others PIPE_FORMAT_Z24_UNORM_S8_UINT, some both. It doesn't matter which one we use, since the d3d formats they map to aren't lockable (app can read it directly).
