This method uses signaling (through a boolean) and I feel like it's
extremely hacky, but I tested this and it (kind of?) works.
Unfortunately I found this to potentially lag when resizing.
I am not sure if this is guaranteed to work (as in, produce correct
behaviour) or not, but to my understanding only LogicDialog uses LCanvas
(grep out "LCanvas\|canvas" and see) so it will most likely work?
I tested this and accidentally found an unrelated issue related to
LCanvas.maxJumpsDrawn, but I hope this will be fixed in the near future.
