This happens on NVidia GPUs, using more textures than the maximum allowed by the gl will NOT trigger a linking issue (maybe because of bindless texture implementation?). So in this case we manually count the number of samplers per shader stage and compare it against the GL limit. We discard the shader if the sampler count is too high. This shows the user something is wrong with the shader.
