// to night and day cycles

// FIXME!
//
// There's a bit of a bug with this implementation
// when the user speeds up the time to 20X...
// the sun/moon orbit will become out of sync with 
// the engine time (which controls the traversal of 
// the lookup table) so at times, the sky may 
// not fade at exactly the right time...
