[Mesa-dev] [PATCH] i965: Disable depth writes when depth test is GL_EQUAL.

There's no point in performing depth writes when the depth test comparison function is set to GL_EQUAL - it would just write out the same value that's already there (if it is written at all). While this is harmless from a functional perspective, it hurts performance. Obviously, writing to memory
