Add MinRange support to AffectsShroud #17449
This is then used to remove the overlap between the two vision traits on RA actors. Testing against
This shouldn't conflict with #17383, and may give us a much smaller (possibly negligible) improvement on top of it. In any case, the minimum range support may be useful for modders.
This also fixes the bogus vision definition for the allied tech center in RA to avoid having a minrange > maxrange.
I think adding support for minimum sight ranges is a good modding enhancement regardless of it's effect on performance and I don't see any direct conflicts with #17383 because that doesn't really touch upon the actual sight range calculation part.
The performance gains when added on top of #17383 would probably be a lot less though.
