This class performs refraction computations, following literature from atmospheric optics and astronomy.
Refraction solutions can only be approximate, given the turbulent, unpredictable real atmosphere. Typical horizons do not go down below -1, so strange effects (distortion) between -2 and -5 should be covered. Note that forward/backward are no absolute reverse operations! All the computations should be in effect (1) only if atmosphere effects are true (2) only for celestial objects, never for landscape images (3) only for terrestrial locations, not on Moon/Mars/Saturn etc
