Broadening the Use of the VRay Map

[jkletzien]

Really like the idea of the VRay Map, as a way to employ the VRay raytrace generator outside of the reflection color/intensity, but am frustrated that it doesn't seem to work in any slot but the reflection or refraction.

Would really like the option to use this in other areas, like in an opacity slider, or a blend, or mask in order to get some more abstract effects.
