[Piglit] [PATCH 11/15] arb_tessellation_shader: Negative test mismatching shader and primitive type.

Mon Mar 24 15:02:50 PDT 2014
>From the ARB_tessellation_shader spec (Errors section):
"The error INVALID_OPERATION is generated by Begin (or vertex array
commands that implicitly call Begin) if the active program contains a
tessellation control or evaluation shader and the primitive mode is not
PATCHES.
The error INVALID_OPERATION is generated by Begin (or vertex array
commands that implicitly call Begin) if the primitive mode is PATCHES if
either:
* the active program contains no tessellation evaluation shader, or
* no program is active."
