Steve,
I don't want to 'fix' it. There are too many applications for the MIRROR function as it works today*). If I read you
correctly, you don't want the object mirrored x- and z-way, but duplicated around the y-axis.
So maybe I can create a new function that takes care of that. I've already made a separate program that does this, so it
shouldn't be impossible to implement it into LDS.

*) Just one example: I used the MIRROR function on the Pirates Flag. Viewing it from the front, the rugged part points
to the right. Viewing from the back, the rugged part points to the left. That's what I call mirroring. If the MIRROR
function had *rotated* each line, the back side of the flag would have looked scrambled.
