- drdTheta
- change in radius per revolution
- startZ
- starting z value
- dzdTheta
- change in Z per revolution
- startXform
- starting contour affine transformation
- dXformdTheta
- tangent change xform per revolution
- startTheta
- start angle in x-y plane
- sweepTheta
- degrees to spiral around
Generalized Torus. Similar to gleSpiral, except contour is a circle. Uses
gleSpiral to draw.
