Hi folks,

can someone check whether `scenes/portfolio/allobjects.pov` does indeed 
showcase all geometric primitives implemented in POV-Ray v3.8, and if 
not, come up with a neat sample scene for any that are missing?

It does 27 objects.
"bicubic_patch", "blob", "box", "cone", "cubic",
  "cylinder", "disc", "julia_fractal", "height_field",
  "isosurface","lathe","mesh","parametric","plane",
  "polygon", "poly", "prism", "quadric", "quartic",
  "smooth_triangle", "sphere", "sphere_sweep","superellipsoid",
  "sor", "text", "torus", "triangle"

I did not see:
conic_sweep, julia_fractal, lemon, ovus, mesh2, polynomial, sky_sphere


And wasn't sure if julia and sky_sphere were "objects".
Also, should there be a polynomial in addition to poly, just to test the
redundant keyword functionality?

Is the content of 'Shapes2', 'Shapes3', and 'Special shapes' relevant? 
It is absent.

Adding the mesh2 is not useful as the only difference is in how the 
definition is written. The internal representation and rendered result 
are identical.

conic_sweep is a modifier for the prism object. It would be nice to show 
one with the conic_sweep option used.

julia is a pattern that you can apply to any object.

sky_sphere is not an object but a background feature.
