/** \class TELTU
\ingroup g3d
A cylinder with an elliptical section. It has three
parameters: the  ellipse  semi-axis in X, the ellipse
semi-axis in Y  and the half length in Z. The equation of
the conical curve is:
 
     X**2/fRx**2  +  Y**2/fRy**2  =  1
 
ELTU is not divisible.
 
  - name:       name of the shape
  - title:      shape's title
  - material:  (see TMaterial)
  - rx:         the  ellipse  semi-axis   in  X
  - ry:         the  ellipse  semi-axis   in  Y
  - dz:         half-length in z
