I've just come across another subtle flaw in the code-- NOT normal-related--
that's probably been there since my *early* experiments. I may have introduced
it with my own fixes, I don't know. Basically, *sometimes* the arrow or 'new'
object suddenly flips from one side of the preview render to the other. But it
happens only with certain juxtapositions of camera and lookat point, and their
positions relative to the x/y plane at the origin. It's strange that I didn't
see this flaw previously, even after 100-plus tests of the code! (All my
previsous tests just happened to avoid this situation, amazingly.)
Luckily, I've been able to deduce the 'rules' that govern this behavior, so I'll
add a fix for it-- as soon as I figure out how ;-)
