In certain types of animation it's possible to have some objects scaling to zero. In this case we can save render times by avoid traversing such instances. Better to do ti ahead of a time, so traversal stays simple. Reviewers: lukasstockner97, dingto, brecht Reviewed By: brecht Differential Revision: https://developer.blender.org/D2048
