+/// Use this component to opt-out of the built-in CPU frustum culling, see
+/// [`Frustum`]. This can be attached to a [`Camera`] or to individual entities.
+///
+/// It can be used for example:
+/// - disabling CPU culling completely for a [`Camera`], using only GPU culling.
+/// - when overwriting a [`Mesh`]'s transform on the GPU side (e.g. overwriting `MeshInputUniform`'s
+/// `world_from_local`), resulting in stale CPU-side positions.
