variable: $wcpx -- cmplx ang err force sphere_morph()
-------------------------------------------
default: 0.0

The floating point parameter, $wcpx ("weight of
complex angle error"), (F3 panel, lower left)
controls the strength of the tangential 'force'
in sphere_morph() that tries to reduce error
between the complex angle on the moveable and
target surfaces.

Turning this up produces better alignment at the
cost of more distorted surfaces.

See R-click help for "REG" for more details.
