I forgot to add: The numberbox labelled "radius" is not used to input
the actual radius although with a different scaling it can be made
to do so.

For simplicity it is scaled by cos(360°/16) which is about 0.92, and
sin(360°/16) (about 0.38), which explains the 38 and 92 inside the
data structure definition.
