A general trapezoid.

A general trapezoid is one for which the faces perpendicular to z are trapezes but their centers are not necessary at the same x, y coordinates.

It has eleven parameters: the half length in z, the polar angles from the center of the face at low z to that at high z, H1 the half length in y at low z, LB1 the half length in x at low z and y low edge, LB2 the half length in x at low z and y high edge, **TH1** the angle with respect to the y axis from the center of low y edge to the center of the high y edge, and H2,LB2,LH2,TH2, the corresponding quantities at high z.
