The `ClipPlane` enum is being looped over at run-time performing run-time dispatch to determine the comparison operation in `point_within_clip_plane`. Change this `for` loop to be linear code which dispatches using a template parameter. This allows for the `point_within_clip_plane` function to do compile-time dispatch. Note: This linear code can become a compile-time loop when static reflection lands in C++2[y|z] allowing looping over the reflected `enum class`.
