Wings appear completely black (no textures) on configurations using OpenGL v3.3 or lower

@Crzyrndm please ignore for now - this is the same issue as discussed on the forums, posted here for the benefit of others who check github first. (If that's you - the forum link has relevant information for 2 pages ATM).

The parts appear textured and striped in the part browser; and have pitch-black surfaces when placed, with a normal texture on the side. Example screenshot by Konnor.

The issue seems to originate from Unity, possibly compounded by video drivers (Unity only claims support for vendor-provided drivers AFAIK).

JIC, my system:

• Arch Linux 64-bit;
• open-source Radeon drivers (xf86-video-ati 7.7.1);
• KSP 1.1.3 (started with LD_LIBRARY_PATH="/usr/lib:$LD_LIBRARY_PATH" LC_ALL=C ./KSP.x86_64 -force-glcore45 -adapter 0);
• B9-PWings-Fork 0.40.7 (installed via CKAN as a dependency for RP-0).

For clarity: source: This is an issue with the shader under an older version of open gl (3.3 or lower). Check logs of affected games for actual version used (ie. while the command switch listed indicated opengl 4.5, unity will fallback if that is not possible. The log records the actual version used)
