Given a point measured and expressed in the base frame F, determine whether it is strictly contained in the box (just touching doesn't count).
Cost is about 23 flops.

Stretch this box in place by a small amount to ensure that there will be no roundoff problems if this is used as a bounding box.
The amount to stretch depends on the default tolerance for this precision, the dimensions, and the position of the box in space. A very large box, or a box that is very far from the origin, must be stretched more than a small one at the origin. Cost is 6 flops.
