Ray-Tracing now handles IBL and background cubemaps in similar way as PBR. Ambient light source is handled by Ray-Tracing in similar way as PBR, e.g. as coefficient for environment map (IBL) or as constant light source. Test script generating PBR spheres has been moved to Samples and now shared by PBR and Path-Tracing tests.
