Instead of checking the API variant on entry of set_varying_vp_inputs to check if we can ever be interrested in fixed function processing or not, we can check if we are actually fixed function processing. To check this we can use the immediately updated gl_context::VertexProgram._VPMode value that tells us if we have a user provided shader program or if we are in fixed function processing either through an internal TNL shader of directly through hardware. When doing so, we also need to recheck the varying_vp_inputs variable at the time gl_context::VertexProgram._VPMode is set to VP_MODE_FF. Put asserts at the consumers of gl_context::varying_vp_inputs to make sure gl_context::VertexProgram._VPMode is set to VP_MODE_FF. By that gl_context::varying_vp_inputs should be up to date then. By not looking at the opengl api for this decision we should actually catch more cases where we can avoid setting a state change flag, including the ones where we cannot get into VP_MODE_FF by the choice of the api.
