I'd like a flag to be added that lets you have right click only show objects on tiles that you can right click without your mouse being obstructed by the blackness tiles generated by those two flags.

Why:

SEE_PIXELS is very powerful. Remember when I was complaining about SEE_INFRA? I don't need that at all - SEE_INFRA for selective through wall visibility is not nearly as good as SEE_PIXELS, as the SEE_BLACKNESS plane (0) is actually something that we can manipulate with a plane master. With this, I can attach overlays to objects' vis contents and have them show up on planes above the blackness planes (so through walls) without jumping through many, and potentially *costly* hoops which I'd have to do with SEE_INFRA.
