-/**
-Stores properties of a single light source.  Lights can be directional, point
-lights or spotlights.  No explicit type parameter is provided; rather the
-other parameters determine what kind of light it is.  If the fourth component
-of position is zero, it's a directional light.  Otherwise, if the spot cutoff
-is not 180 degrees, it's a spotlight.  Otherwise it's an omnidirectional point
-light.
-
-Lights are usually grouped with a Lighting object, which can be used in a
-Pipeline::Pass.
-
-Lights do not cast shadows by themselves.  See ShadowMap for that.
