partial torus prims

[Peter Blomberg]

What about updating the naming as follows?

sweep:

first number states the number of segments
second number states the resolution (8, 16, 48)

1-8
11-16
11-48
8-8, 16-16, and 48-48 would be full circles in different resolution

tori:
major sweep + "t" + major radius + "i"/"o"/"p"/"q"/"t" + minor sweep + "m" + minor radius

The 'i'nner starts from major-minor
The 'o'uter starts from major+minor
The 'p'erpendicular starts from major and continues inwards (toward major-minor)
The 'q' starts from major and continues outwards (toward major+minor)
A 't' contains the whole tube (2 inner + 2 outer) (minor sweep and "m" not needed)

cones and rings:
major sweep + "con" + major radius (minor assumed 1)
major sweep + "ring" + major radius (minor assumed 1)

cyls:
"cyls" major sweep + "i"/"o"/"p"/"q" + major radius
i starts from the low end, currently cyls
o starts from the high end
p starts from the middle and continues toward the low end, currently cyls2
q starts from the middle and continues toward the high end

spheres:
"sphe" major sweep + "i"/"o" + minor sweep
i starts from pole
o starts from equator (where major sweep is defined)

the "one-eight" of a sphere would be sphe4-16o4-16
a shallow puddle would be sphe16-16i1-16
