       Resolution: Fixed
    Fix Version/s: 5.3
         Assignee: David Smiley

bq. If you are waiting for Nicholas, I fully agree, but he's on paternity leave so it may
be quite some time. Might be better to commit and revise later, if needed.

Committed now.

It was a nice-to-have, plus I was/am busy.

Thanks again for WGS-84 support!  You made it look so easy :-)

> WGS84 compatibility has been requested for geo3d.  This involves working with an ellipsoid
rather than a unit sphere.  The general formula for an ellipsoid is:
> x^2/a^2 + y^2/b^2 + z^2/c^2 = 1
