   In order to inline this calculation, I make the risky
   assumption that all filter patterns can be described
   by a repeating pattern of eight rows and two columns

   Do not use the FC or BAYER macros with the Leaf CatchLight,
   because its pattern is 16x16, not 2x8.

   Return values are either 0/1/2/3 = G/M/C/Y or 0/1/2/3 = R/G1/B/G2
