/*
Persistence of Vision Raytracer Version 3.5
IMPORTANT!
This collection of standard shapes has been around since the days
of DKB-Trace and early versions of POV-Ray. Those versions had no
optomized primatives for planes, cones, disks etc. Some of the definitions
below may seem trivial or unnecessary given the POV-Ray 2.0 and higher
object primatives. We have retained these objects for compatibility with
earlier versions.
With the release of POV-Ray 1.0, some of these shapes, in particular,
the "Disk_?" group, were changed from an earlier beta test and DKB-Trace
style. The file "shapes.old" is also included in this package for
compatibility with pre-1.0 scenes.

//2001.7.27: renamed as shapes_old.inc for POV 3.5. The new shapes.inc
//file includes this file, so backwards compatability is preserved.
