Colored Fog Issues

[NeuralStunner]

Semi-crossposted from ZDoom forum, as GL has a few different issues here.

Noted problems:

1. 3D sector fog is too dark, as with ZDoom.
2. The interior of the red area appears too "thin" for having 0 lighting (100% thickness).
3. Inside the red area, the floor/ceiling are tinted for default lighting, not the sector's fog. Same for sprites (including HUD). All appear black.

Example map in the ZDoom forum post.

Unfortunately here you can see the difference between software fog and hardware fog. The software fog hijacks the lighting to do its work which in certain situations creates strange effects. Hardware fog does not do this and does not know 'total opacity' and I'm not going to change the system.

Ah, okay. I've at least got water looking how I want it, I'll need to think of another way to make thick liquids "opaque".
