From a03d6f2aa3bb589ca61c3cc13c4189a973b3a2c1 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Mon, 15 Feb 2016 23:57:06 -0500 Subject: mesa: add GL_OES_texture_stencil8 support It's basically the same thing as GL_ARB_texture_stencil8 except that glCopyTexImage isn't supported, so add STENCIL_INDEX to the list of invalid GLES formats for glCopyTexImage.
