Do ALL the jitter objects use openGL or just the jit.gl.objects ?

jit.gl.objects use openGL  and are therefore not usable with most usb monitors as they do not
support openGL .. BUT .. does that mean that All jitter objects use openGL or is it only  the jit.gl.object ?
i want to use jit.brcosa jit.sobel jit.robocross and jit.qt.grab/jit.dx.grab   .. are they using openGL and if yes how to disable it ? I have been seraching after the answer a while .. i hope that someone here got it
best reggards
