[Bug] povray quiet mode is not quiet

[ConduitDan]

running povray in quiet mode doesn't silence it, instead it run it in a new process

Working on adding minimal example

This is working on macOS... the povray module pipes stdout to dev/null as follows:

&> /dev/null

I'm guessing this doesn't work on some linuxes [or maybe WSL?]..? What's the equivalent?
