For an ESG map with parameters, (A,K), and geographical orientation, given by plon,plat,pazi (radians), and given a point in grid-space units as the 2-vector, xm, return the geographical coordinates, lat, lon, (radians) of this point.

If instead the transformation is invalid for any reason, then return the raised failure flag, FF=.true.

Parameters
[in]aparameters of the ESG mapping
[in]kparameters of the ESG mapping
[in]platradians latitude of the projection center of the mapping
[in]plonradians longitude of the projection center of the mapping
[in]paziAzimuth of the orientation of the mapping at its center
[in]delxcentral x-spacing of the grid in radians
[in]delycentral y-spacing grid point in radians
[in]xmgrid-space 2-vector coordinates of a point to be mapped
[out]latradians latitude of the point
[out]lonradians longitude of the point
[out]fffailure flag

[in]kparameter of an ESG mapping
[in]platradians latitude of the projection center of the mapping
[in]plonradians longitude of the projection center of the mapping
[in]paziAzimuth of orientation of the mapping at its center
[in]xmcenter-relative 2-vector map space coordinates of a point
[out]latradians latitude of the point
[out]lonradians longitude of the point
[out]fffailure flag
