hm, I don't think we have a wrapper for that in 1.x (or 2.0 FWIW), at least I
did not see anything obvious.
The quick, one shot, way is to just issue the glReadPixels() call after
rendering, before Window::frameExit() runs.
A better integrated way would be to create a DepthGrabForeground or perhaps
extend the existing GrabForeground to make the necessary OpenGL calls - should
not be very difficult, OSGGrabForeground.cpp is just 170 lines ;)
Cheers,
Carsten
