shadows in game sun is opposite to structure shadows

[Berserk Cyborg]

Speaking of shadows, I think we should draw in the order of opaque models->shadow->translucent models rather than drawing shadows first. Still, base plates are considered translucent (?) and shadows will not draw over them and the CC antenna looks worse than ever because of #4093.

The base plates should show shadows and where alpha overlaps alpha they just go all stupid this has been a long time bug in the graphics.
Im sure we can compile a huge list of bugs but fix the direction of the sun and the structure shadows this is long needed fix.

[Per]

Instead of assuming that all baseplates need to be translucent (do anyone of them actually need to be?), we should read this information from their PIE files. Hardcoding this kind of information is just silly.

[Berg]

The pie files for base plates are just 2 poly with image co-ords.
I'll check them but I do think the properties for them are either hard coded or shadows don’t fall on my structure pie files?
