[OSRS-PROJ] Proj.4 vs Geotrans

[Gerald I. Evenden]

A followup note: reading the Mercator code realized the fact that
although you could spec the scale factor at the equator
(equivalent to +k_0=) there was no latitude of true scale
(+lat_ts=) that, from my experience, is the most common usage
for Mercator (look at the bottom of navigation charts).
