ELEMENT VOLUME DATA:

For centered elements with plane or spherical circular faces, exact
volumes are computed by assuming edges are squared up to the larger
of the front and back radial aperture.

For all other elements, approximate volumes are numerically integrated
to 0.1% accuracy. Zero volume means the volume cannot be accurately computed.

Single elements that are duplicated in the Lens Data Editor
for ray tracing purposes may be listed more than once yielding
incorrect total mass estimates.
