New Revision: 7248

Modified:
   trunk/darkplaces/gl_rmain.c
Log is attached.
fix glsl model lighting on unlit maps (normal vector was calculated as (0,0,0) as there was no contribution from the map -> GLSL calls normalize() on that -> (nan,nan,nan), which apparently counts as black).
The fix replaces these zero normal vectors by (0,0,1) (which vector is actually chosen does not matter, as its contribution is scaled by zero anyway).
