[Therion] Point Debris AUT uses wrong pen with clip off if outside of passage

Hi Has anyone else noticed that for the point debris AUT with -clip off it will draw with a heavy weight pen of part of the symbol is outside of the cave passage? While the effect is perhaps OK in the green example below, it looks a bit odd in the blue example. -clip on for point debris, and -clip off for point debris I am not sure why it would do this. Seems to be nothing in the point definition that should cause this (to my inexperienced eye). Maybe something in thdraw? Bruce
