How would I go about reading the Z-Buffer of an SoOffscreenRenderer's
image? I assume I'll need to make OpenGl calls in my code immediately
after performing the render(). Presumably I need a glReadBuffer to set the
buffer to the offscreen buffer - except I don't know how to specify this
buffer - is it a GL_AUX or something else?
