+14-bit Bayer formats expanded to 16 bits
+
+
+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 14 bits per
+colour. Each sample is stored in a 16-bit word, with two unused high
+bits filled with zeros. Each n-pixel row contains n/2 green samples
+and n/2 blue or red samples, with alternating red and blue rows. Bytes
+are stored in memory in little endian order. 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, the two most significant bits in the high bytes are
+zero.
