Merge duplicate umbra points in spot shadow.
When we search for the closest umbra point at the end of the shadow
creation process, we often find the umbra point we first added.
Previously we would add this point again and patch up the result.
This is causing issues with fixing the falloff, so this code handles
this case better by reusing the original entry in fPositions.
