--- Comment #8 from José Fonseca <jfonseca at vmware.com> ---
Yes, I suspect that ideal MRD at near plane may never go below 2, because of
the the "near_1_far_infinity" perspective transformation applied.

We could experiment whether an orthogonal transformation would allow to tease
an ideal MRD of 1.

Another solution would be to compute the minimum MRD, not from this complex
procedure, but from the glGetIntegerv(GL_DEPTH_BITS).
