-- Vertex Color Killer 1.0
-- Destroys vertex alpha, illumination and color data on the current selection.
-- By Smallpoly (Michael Vladimir Nicolayeff), 2016

-- Does not currently collapse the objects at the end. This makes it simpler to remove from objects that don't need it if they were accidentally selected.
-- Does vertex alpha first, then illumination, then color.
