I know, virtually nobody is using it, so who cares?
But the one person that does need this projection in the general sense, can
do absolutely nothing with the ArcGIS fudge factor of -2299363.487823496 if
he wants to project from another ellipsoid or with another latitude of true
scale.
This needs another fudge factor or more sensibly, an equation.
