This version of the commit has the on_ceiling/on_wall fix without any explaination of that code, since apparently it wasn't complicated enough. As for the notes at the top of the function, they're still there. move_and_slide is rather useful for character-controllers, etc. It reduces the amount of boilerplate code. Not having move_and_slide makes the APIs somewhat inconsistent. (It might be nice to figure out a way to share the code between the two move_and_slide implementations, but that's for someone who knows what the policy is on shared code like that.)
