- 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
