SceneRefract: Updates to compute refraction vectors through the front and back
of the object.  This required adding a color target for the first pass so that
we can store the surface normals from the back side of the object.  Still need
to determine whether or not to factor in the distance from the front to the
back of the object (else the distance map may not be needed and we may not need
the depth target in the first pass).
