14-bit packed Bayer formats


Description
===========

These four pixel formats are packed raw sRGB / Bayer formats with 14
bits per colour. Every four consecutive samples are packed into seven
bytes. Each of the first four bytes contain the eight high order bits
of the pixels, and the three following bytes contains the six least
significants bits of each pixel, in the same order.

Each n-pixel row contains n/2 green samples and n/2 blue or red samples,
with alternating green-red and green-blue rows. They are conventionally
described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example
of one of these formats:

**Byte Order.**
Each cell is one byte.
