Would it be possible to add an option to disable the sky reflection on stained glass.

[PFleur]

I've found this shader to be the best for glass given how it colours light which passes through but the sky reflection giving stained glass a blue sheen really reduces its potential and as such having the option to disable it would do wonders. I don't know how much would have to change or whether it would be worth it but this doesn't seem to be all that uncommon of a sentiment.
