Author: Kenneth Graunke <[email protected]> Date: Thu Mar 20 11:53:16 2014 -0700 mesa: In core profile, refuse to draw unless a VAO is bound. Core profile requires a non-default VAO to be bound. Currently, calls to glVertexAttribPointer raise INVALID_OPERATION unless a VAO is bound, and we never actually get any vertex data set. Trying to draw without any vertex data can only cause problems. In i965, it causes a crash.
