Comment (by knarf):

 Con2Prim currently uses the old values of the primitives as input to
 calculate the new values. Calling it multiple times would potentially
 change the primitives each time, because a minimum number of iterations is
 done by default, by default at least 1 iteration. We either need to change
 this and thus, make a second call to Con2Prim a noop because the solution
 is already present (but this might be difficult if other routines change
 this, like atmosphere treatment), or we need to decouple the initial
 guesses from the output primitives. Given that we would actually like to
 have the latter for con2prim anyway (save the initial guesses to have
 separate tries for con2prims) I would like the second approach more.
