These formats are compressed 14-bit raw bayer formats with four different
pixel orders. They are similar to 10-bit variants. The formats added by
this patch are

+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.
