The cartesian axes use animSpeed to animate changes. Instead
of passing down the value to the respective functions, the
speed was stored in the ProfileScene and the axes would
access it there. Very messy. Let's just pass down the speed.
There still are back-references from the axes to the scene,
notably to place labels "outside" of the scene. Let's try
to remove them later.
