Modding settings.txt OK for stock PBW games?

[geoschmo]

The "mask background objects" setting doesn't make invisible objects visible. They are either visible or invisible depending only on game factors like the obscuration of the nebulae and the players sensor level. What the mask background objects does is when they do become visible due to sensors they will have a funky square around them if they are in a nebulae unless you turn that on.
