-de code voor de animaties is nog niet compleet af, animatie 1 en 3 doen het
-inmiddels, maar 2 heeft nog wat problemen door de `fill_plane` functie. deze ga
-ik opnieuw implementeren en woensdag testen.
-
-ook het algoritme om lege scanrijen over te slaan is nog niet afgewerkt en
-wordt dus ook op woensdag getest.
