Thanks Gilles, Rune.

FYI, this is for enhancements to a set of animation macros, and this 
question was for a subset that would wrap around the animation portion 
of the script and could be switched on/off by commenting a line or two.

The intent of the subset of macros is to allow tweaking the movements 
and *QUICKLY* generate a single image to see the motion.  And then 
repeat as needed.

Although I like the visual effect of the "echoes" for its own merit, I 
wanted this as a additional information when the user tries to verify 
proximity of objects, the shape of a path, or things of that nature.

The subset of macros works now -- but without any fading.  I'd hoped 
that adding fade would be less difficult.  Oh well.

PS: The macro package (called "TikTok") is a work that I started mid '03 
and showed to Gilles in Aug'03.  I'm just now getting back to polishing 
it up, with examples & some reasonable docs.
