Convert projection coordinates to lat/lon coordinate.

@param from array of projection coordinates: from[2][n], where
(from[0][i], from[1][i]) is the (x, y) coordinate
of the ith point
@param to   resulting array of lat/lon coordinates: to[2][n] where
(to[0][i], to[1][i]) is the (lat, lon) coordinate of
the ith point
@return the "to" array
Convert projection coordinates to lat / lon coordinate .
