Blend Normals Node

The Blend Normals node blends two normals using the Whiteout Blend method. Instead of just averaging both normal maps, they are calculated the following way:
BlendedNormal = normalize( float3( A.xy + B.xy, A.z*B.z ).
This way details, which would have been lost on an regular average, are better preserved.
