* Test that DrawBuffers() returns correct error message for different values

* array passed to DrawBuffers, and will result in the error INVALID_ENUM."

* "If the GL is bound to the default framebuffer and DrawBuffers is supplied
* with a constant (other than NONE) that does not indicate any of the color
* buffers allocated to the GL context by the window system, the error
* INVALID_OPERATION will be generated."
