Please find enclosed two renderings of the exact same scene file, one with
povray 3.7.0 official, the other with 3.6.  The scene file contains several
characters. Some are very complex blobs (whereby individual components undergo
multiple, compound transformatios), and have a complex texture applied to them.
The "wooden guy" (3rd in back row) is however nothing but simple spheres
(undergoing the same complex transformations).

Note that the people are all missing with 3.7!

If there were some new rule-of-thumb that would allow me to quickly fix the
scene, please let me know.  Could it be that povray is "not allowing" compound
transformations?

Here are just a few lines of the (possibly offending) code, which explain what I
mean by compound transformations:
