Implement reflection (except for the diagonal corridor case).
Reflection is modelled on diamond-shaped features, with gaps
filled in as far as they don't affect LOS.
Working on a case by case analysis: After normalization, a ray
leaves cell * through the south-east diamond face. Then determine
the line of reflection in each case.
