Detailed Description

Truncate a bounding zone using a convex quadric surface.

Convex surfaces are planes, spheroids, cylinders, parabolic cylinders, and paraboloids. All but the spheroids are infinite in at least one direction.

This reduces the size of inner and outer bounding boxes to fit a surface. The interior bounding box is modified to be entirely inside the surface, and the exterior is modified to be entirely outside. Axes that cannot be determined inside or out are left unchanged.

Even though most quadric surfaces are infinite, their intersection with a bounding box may be a smaller bounding box. Accounting for the current bounding box's size when considering further truncation is not yet implemented.

Shrinking bounding boxes will accelerate "distance to in" and "distance to out" calculations.

TODO: move to orangeinp/detail, use BZone, combine with NegatedSurfaceClipper.
