start and end values could be specified as float arrays (maybe set method too)

example:

Transition t = ...

t.set(50f, 50f);

and/or

Vector2f v = ...
Transitions.transitionBuilder(v).end(5f, 10f).time(500);

Mutable transitions allow that, but one problem is that implies creating new float[] on each call, the user has to cache values by himself.
