Detailed Description

Region formed by extruding + scaling a convex polygon along a line segment.

The convex polygon is supplied as a set of points on the XY plane in clockwise order. The line segment and scaling factors are specified by providing a line segment point and scaling factor for the top and bottom polygon faces of the region. The line segment point of the top face must have a z value greater than that of the bottom face. Along the line segment, the size of the polygon is linearly scaled in accordance with scaling factors.

As is done in Geant4, construction is done by first applying scaling factors to the upper and lower polygons via scalar multiplication with each polygon point, then the points on the line are used to offset the upper and lower polygons.
