[visionegg] Usage of OrthographicProjectionNoZClip

I'm a little confused about the purpose of the
OrthographicProjectionNoZClip class. When I instantiate one like this:

   OrthographicProjectionNoZClip(0, screen.size[0], 0, screen.size[1])

OpenGL still appears to clip in the [0,1] range. I ended up having to do:

   OrthographicProjection(0, screen.size[0], 0, screen.size[1], min, max)

to get what I wanted. Is this class really for something else, with
perhaps a misleading name? Or am i misunderstanding it's purpose?

Thanks,

Simeon
