What a surface analysis shows at each point of a face. none leaves the faces as they are; gaussian
and mean are the Gaussian and mean curvature, maxCurvature and minCurvature the two principal
curvatures, positive where the face bulges out; minRadius is 1 over the larger principal curvature,
infinite where the face is flat; draftAngle is the angle in degrees between the face and a pull
direction, positive where the face looks along the pull.
