// D3D9 has a special codepath that rearranges the input layout sent to D3D,
// to ensure that slot/stream zero of the input layout doesn't contain per-instance data, so
// we test with attribute 0 being instanced, as will as attribute 1 being instanced.
//
// Tests with a non-zero 'offset' check that "first" parameter to glDrawArraysInstancedANGLE is only
// an offset into the non-instanced vertex attributes.
