Bézier Curves for Gentables

Yeah, but that’s because I’m taking some shortcuts. We’ll probably have to redo it some day.

What do you think of something like this? I had to override the virtual paint function inside HandleViewer. Do you think that’s fine? I’ll probably need to add a bool too to check whether it’s a quadbezier gentable or not.

EDIT: Fixed some things with the latest commit.
