From 12c43a355c6a8812319dea661480488ed198ed06 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 26 Apr 2016 02:31:20 -0700 Subject: [PATCH] mesa: Try to fix CopyTex[Sub]Image of stencil textures. ES prohibits this, but GL appears to allow it. We at least need this much, or else we'll crash as there's no source to read from. This fixed crashes in the ES tests before I realized I needed to prohibit stencil instead.
