[Piglit] [PATCH] arb_blend_func_extended: add three api tests
Dave Airlie
airlied at gmail.com
Sun Nov 20 11:00:41 PST 2011
From: Dave Airlie <airlied at redhat.com>
The first two are heavily reused version of the gl-3.0 API tests from Ian, just
adapted to test the two APIs for GL_ARB_blend_func_extended,
the third is a simple test that glBlendFunc can accept the new tokens, and
the changed behaviour of the GL_SRC_ALPHA_SATURATE token.
