Sanic noticeably jiggles while moving when there is frame lag

It's hard to tell if it's the camera or Sanic causing the visual choppy position jumping. It looks like we're applying delta correctly in most places, but we aren't always doing the right type of interpolation.

For instance, the camera movement is done with linear interpolation with the weight as a factor of delta time, but it really should be asymptotic interpolation. I don't think there are functions in Godot for it, so we should maybe make a global utility script.

I now suspect that this has to do with the underlying physics engine, because the stuttering also happens to the basketballs at the same time, which are RigidBodies (opposed to sanic, which is a KinematicBody with a bunch of gdscript controlling it).

It may be a good idea to try placing everything relying on the location of the player into the fixed processing pipeline. This would make the jiggling not seem quite as dramatic when it happens.
