[EdJoPaTo]

See #978

Also remove other derives. They are unused and just slow down compilation.

Hey, this looks good to me, thanks for this.

Had a little comment but it's non-blocking.

[EdJoPaTo]

It might be a good idea to split the canvas changes from the rest of this PR as it has also changes to the code behavior?

[Valentin271]

Surely I'm forgetting/misunderstanding something... Canvas doesn't have a change in behavior ..?

[EdJoPaTo]

Canvas doesn't have a change in behavior ..?

The checks and math logic has changed. That might have changed something. It's not much so it could be fine to mix it.

I think you might be referring to the Chart (not canvas)
If it didn't break the tests (and those lines are covered by tests) then I'm not bothered too much.
