Draw polycylinder, specified as a polyline.

Note that neither the very first  segment,  nor  the  very
last  segment are drawn. The first and last segments serve
only to define the angle of the join at the very  ends  of
the  polyline.  Thus,  to  draw one segment, three must be
specified. To draw two segments, four must  be  specified,
etc.

The color array may be NULL. If NULL, the current color is
used. If not NULL, the glColor3f() routine is used to  set
the  color;  therefore,  specifying  the glColorMaterial()
subroutine before this primitive can be used to  set  dif-
fuse, specular, ambient, etc. colors.
