In the limit where the distance between the two central points AB
vanishes tpeqd degenerates to the azimuthal equidistant projection (the
spherical variety because tpeqd is only implemented for a sphere).  So
if you're projecting a point C and CA >> AB and CB >> AB, you might get
more accurate results using aeqd.
