For spotlights, I believe the documentation for the coneangle parameter is incorrect. At the end, it states:
After this angle and up to "coneangle" + "conedeltaangle", illumination falls off until it is zero.
Shouldn't this be coneangle - conedeltaangle? That seems to match up better with what is described in the online editions here and here.
