OpenGL2:

Bug/issue:
Some texture/shaders stays visible inside a fog volume. Visibility of these textures/shaders should decrease (as with renderer1).
This issue happens to some items (see attached screenshot), impact wallmarks, blood sprites, flame textures and so on.

How to reproduce:
Start any map with a fog volume (e.g.: q3tourney5). Fire some bullets on walls and have alook at them over long distance through fog. The impact marks remains visible. Or have a look on 'health items' glow texture, they also remains visible even on long view distance. The same is true for flames on torches, blood sprites etc.

Note:
An expert told me: "Fog color/settings are suppose to be applied to each surface drawn, but is not."
This might cause the bug!

Thank you!
