NonConformalMapT node is working.

Preliminary layout of enhanced ConformalMapT:

Scaling to say 98% of Torus tube diameter may be accomplished by vector subtraction.
let vecA = vector (point) from origin to the conformal point on torus surface.
vecB = vector (point) from origin to center of rCircle. (The rCircle passing through the conformal point.)
vecC = vector (point)from said center of rCircle to conformal point on surface of torus, (which is parallel to the surface normal there).
vecD = scaled vecC.
vecE = vector (point) from the origin to the scaled conformal point lying inside of the torus surface, below the conformal point.

vecA = vecB + vecC, so vecC = vecA - vecB.

vecD = vecC * 98%. //scale length.
vecE = vecB + vecD.

Form a curve from the vecE points generated from the many conformal points.
