 * Differences between collection line art usage flag:
 * Collection line art usage is global, used to specify e.g. if a collection should appear in calculation at all.
 * Invert collection selection is used to easily select a collection and "everything else other than that collection", making it convenient to set up such cases.




 * New option to preserve contour lines when using face mark filtering.




 * Noise tolerant chaining. This feature takes advantage of original line art chain which is a continuous long chain, instead of splitting it at each occlusion change, this function tolerates short segments of "zig-zag" occlusion incoherence and don't split the chain at these points, thus creates a much smoother result.
