Chained transformations

Two transformations can be chained.
However, not just any transformation can be chained to another one.
In this case, the following restrictions apply:
● The first transformation of the chain has to be one of the following transformations:
● The second transformation must be aninclined axis transformation.
● Only two transformations may be chained.
It is allowed (for test purposes, for instance), to enter only a single transformation into the
chaining list.
