Clown Pass options

[Speedster]

The automatic Clown Pass that you can request in the Render window recognizes only materials.  Many times we have multiple parts sharing the same material, so they clown as one color.  How about adding a Clown Pass option to clown individual parts as well.  That is, two check boxes- one "Clown Materials" and other "Clown for Geometry".  And be able to render both at the same time as the beauty or other passes.
