They are, but only from an intuitive sense. It seems that type 1 has a
double boundary, for lack of a better word, which is to say there is a white
area, then a colored then it drops sharply as it fades out. T0 has a white
boundary, but fades out much more smoothly from there. Size affects how big
and bright, radius cuts off the glow effect after a distance, and fade power
changes the sharpness of the drop off. That's basically all I needed to
know.

Drat. I was afraid of that. Can you size the glow by intensifying the
color, then, or would that not work?
