Using Animations.jl

[Wikunia]

Regarding #22 where we discuss an easier way of defining frames.

Actually we might want to just define them as animations:
See https://jkrumbiegel.github.io/Animations.jl/stable/

What do you think about:

Action(anim, (args...)->line(O, Point(10,20), :stroke))

where anim is:

Animation(1, Translation(O), sineio(), 30, Translation(Point(20, 50))

but this might be a bit confusing so we should define short hands for it like

Action([1, Translation(O), sineio(), 30, Translation(Point(20, 50)], (args...)->line(O, Point(10,20), :stroke))

or

Action(1:30, sineio, (args...)->line(O, Point(10,20), :stroke), Translation(O, Point(20, 50))

to define a simple animation.

Additionally I'm wondering whether the Translation should be in front of the function as this is the order of execution.

Example of a new idea

Action(1:30, (args...)->line(O, Point(10,20), :stroke); subactions = [
   SubAction(10, sineio, appear),
   SubAction(10, Translation(Point(10,10)),
   SubAction(10, polyin, disappear),
])
