The following two piglit commits are probably necessary:

commit 49e326474d5ed487d04ff6bef1efae376e4a2492

    arb_occlusion_query2: Checks that query obj passed to glBeginQuery matches
target

    From the OpenGL 3.3 spec, section "2.14. ASYNCHRONOUS QUERIES", page 94:

        "[...] if id is the name of an existing query object whose type does
not
         match target, [...] the error INVALID_OPERATION is generated."

    Similar wording exists in the OpenGL ES 3.0.0 spec, section "2.13.
    ASYNCHRONOUS QUERIES", page 82.

    This patch adds a check for this situation.

    arb_occlusion_query2: expect an error when target mismatch in
glBeginQuery()

    From the OpenGL 3.3 spec, section "2.14. ASYNCHRONOUS QUERIES", page 94:

        "[...] if id is the name of an existing query object whose type does
not
         match target, [...] the error INVALID_OPERATION is generated."

    Similar wording exists in the OpenGL ES 3.0.0 spec, section "2.13.
    ASYNCHRONOUS QUERIES", page 82.

    Hence, trying to call BeginQuery on a query object which has already
    been bound to a different target should return GL_INVALID_OPERATION.
