variable: $wcpx2 -- cmplx ang err force sphere_morph()
-------------------------------------------
default: 0.0

The floating point parameter, $wcpx2 ("weight of
complex angle error 2"), (F3 panel, lower left)
controls the strength of the tangential 'force'
in sphere_morph() that tries to reduce error
between the second 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.
