History and status:

Written by Will in GeneratorBaseClass.py, but no longer used there
or by anything that uses it.

bruce 070619 moved this from GeneratorBaseClass.py to its own file. It is deprecated;
its uses should be replaced by rewriting its callers to use the PM package.

Module classification:

As of 071214, it is used only by MinimizeEnergyProp and PovraySceneProp,
which should be rewritten to use PM_Dialog and get things like this file
provides from PM package, so I am classifying it as if it was part
of the PM package. [bruce 071214]
