  Log:
  ccs is a size_t.  RAY_CCS_INDEX takes ccs and does math on it,
  resulting in a size_t due to C's rules of arithmetic.  Rather than
  bogusly cast the result to a uint8_t, fix the printf format specifier
  to have a 'z' modifier which tells the compiler that the sizes really
  do match.
  
  It turns out that change 1.75 was incorrect to assume that this
  'really' was a 8bit quantity.  It isn't.  Although the hardware
  appears to limit things to < 256, it would be a bug that should be
  caught by debug printf it it were.  Casting it to uint8_t would have
  lost this useful information.
  
  Aslo add 'z' to a nearby debug statement that's never compiled in.
