Calculates a geometrical propagation path step.

This function determines a propagation path step by pure geometrical calculations. That is, refraction is neglected. Path points are always included for crossings with the grids, tangent points and intersection points with the surface. The WSV ppath_lmax gives the option to include additional points to ensure that the distance along the path between the points does not exceed the selected maximum length. No additional points are included if ppath_lmax is set to <= 0.
