[Piglit] [PATCH 19/25] arb_direct_state_access: Port copytexturesubimage to core profile
Ian Romanick
idr at freedesktop.org
Mon May 18 13:50:12 PDT 2015
From: Ian Romanick <ian.d.romanick at intel.com>
The "supports_gl_compat_version = 10" was rubbish anyway because DSA
requires OpenGL 2.0 and GL_CLAMP_TO_EDGE requires OpenGL 1.2.
