// was then done to the last vertex only, usually stucking the object sooner

// For instance, the scaling procedure of regular Clonks uses two CNAT_Left-
// vertices (shoulder+belly), which "block" each other in situations like
// scaling up battlements of towers. That way, the 2px-overhang of the
// battlement is sufficient for keeping out scaling Clonks. The drawback is
// that sometimes Clonks get stuck scaling in very sharp edges or single
// floating material pixels; occuring quite often in Caverace, or maps where
// you blast Granite and many single pixels remain.
