[PATCH xwayland v3 1/7] dix: assume warping on the RootWindow always happens on visible coords

[Carlos Garnacho]

If the root window borderClip region is null, the PointInWindowIsVisible()
check fails if pointer warping is attempted on the root window, making
the warping operation bail out early.

Assume coordinates always lay inside the root window for this case,
the actual position will be clamped later within screen coordinates anyway.
