Right, there is no Normal scale afaik.

It seems Emissive color is ignored when an EmissiveMap is set.

          #if defined(EMISSIVE) || defined (EMISSIVEMAP)
              #ifdef EMISSIVEMAP
                  vec4 emissive = texture2D(m_EmissiveMap, newTexCoord);
              #else
                  vec4 emissive = m_Emissive;
              #endif
              gl_FragColor += emissive * pow(emissive.a, m_EmissivePower) * m_EmissiveIntensity;

I agree with you that Emissive color should be used as a multiplier to EmissiveMap. That is how it is done for non PBR glow effect.
