Changed the StaticLightingArrayIntent to use an 'int' argb value as its data store.  I didn'r realize how big a Color was.  This takes the Nutcracker memory in Giz's Canon down to 25 MB (from 91 MB when using Color (which was down from 114 MB when using LightingValues).  I'm a little worried that something has been lost here, but I can't see it.
