Comment (by RyanGlScott):

 Well, somewhat :) But it still has several bulky dependencies, such as
 `vector`, `linear`, `dimensional`, and `JuicyPixels`.

 I suspect there's a small kernel of code that's causing this panic, but I
 don't know how to sort through all of the scaffolding in place to find it
 at present. Since you know this codebase far better than I do, any useless
 code you can remove ("useless" meaning "I can still trigger the panic
 without it") would be of invaluable help here.
