Odd rendering errors with renderpath=vertexshader

[Philip Taylor]

On a GF4, I get distorted models (e.g. some vertexes move to the wrong side of the screen when certain objects are being rendered) when using renderpath=vertexshader, which is fixed with renderpath=fixed. I think I remember we decided the issue was with linking vertex programs together multiple times in different ways, and it could be fixed by duplicating the programs so they were linked once each.

Bobby also reports problems (lighting on models is green when self-shadowing is enabled) which are fixed by renderpath=fixed, on a Radeon 9700 Pro. I have no idea if that is related to the same linking issue, but it'd be worth investigating and fixing.

I get the same on Linux, with

OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce4 Ti 4800 SE/AGP/SSE2
OpenGL version string: 1.5.8 NVIDIA 96.31

[(none)]

vertexshader no longer exists.
