"defaults" argument to Scene() not used?

[thomasbending]

I'm just getting to grips with Vapory, so apologies if I've misunderstood something, but as far as I can see the defaults argument to Scene() is not passed to POV-Ray. I'm using Vapory 0.1.1. On line 52 of vapory.py the defaults argument is used to define a string called defaults, but then this string isn't used. Shouldn't the defaults string be included in the return statement on line 56, or something similar?
