Given the map specification (angles in radians), the grid spacing (in map-space units) and the sample lat-lon (in radian), return the the image in map space in a 2-vector in grid units.

If the transformation is invalid, return a .true. failure flag.

Parameters

[in]	a	parameter of the ESG mapping
[in]	k	parameter of the ESG mapping
[in]	plat	radians latitude defining mapping projection center
[in]	plon	radians longitude defining mapping projection center
[in]	pazi	Azimuth of mapping orientation at its center
[in]	delx	central x-spacing of the grid in radians
[in]	dely	central y-spacing of the grid in radians
[in]	lat	radians latitude of a point to be mapped
[in]	lon	radians longitude of a point to be mapped
[out]	xm	2-vector map space image in center-relative grid units
[out]	ff	failure flag
