3D Viewer: wishlist: add view options: 1) (this report) to subtract SilkS on bare copper, & 2) (https://bugs.launchpad.net/kicad/+bug/1808082): to subtract layers overhanging outside board outline

1) I'd like an option to "subtract silkscreen from bare copper". Most board manufacturers won't print SilkScreen on bare copper, so there should be an option in the 3D Viewer to not show any silkscreen that is sitting on top of bare copper.

2) See https://bugs.launchpad.net/kicad/+bug/1808082.

For both of these new settings, Preferences --> Display Options would be the place to put these new settings. Please add a checkbox for the following:

[ ] "Subtract silkscreen segments on top of bare copper"

See the attached screenshot showing the current 3D Display Options so you can see where these 2 new settings would go.

@Gabriel, I doubt you request will get implemented as a single commit so please break this into two separate bug reports. There is no way in Launchpad to close multiple bugs in a single bug report.

Done.
