ReflectMat

This shader reflects lights into the selected color layer.

If a light is 'delta' type (spot, point) the light will show up as a small disc who's size is determined by the 'light sim diameter setting.  If it is a light that supports textures like Environment or ReflectionCard then the reflected color will be the textured image.  ReflectionCard lights have an accurate spatial relationship to the surface and will properly layer in Z, obeying the light's alpha (as opposed to an environment light which only has a rotational relationship to the surface.)

It also supports multisampling and layered lights, which means that lights which report  their distances accurately will be Z blended together rather than simply added together.  This is necessary to support multiple reflection cards and environment spheres in the same render layer.

Note that the current Environment light shipped with Nuke always reports it's distance as 1 so it will NOT layer correctly, and multiple Environment lights could possibly intersect.

v1.1 update:  Fixed a bug which caused a crash when the map input was used.  Added a blend mode switch to let the user enable/disable Z blending.
