+ <title>Description</title>
+
+ <para>The following four pixel formats are raw sRGB / Bayer formats with
+12 bits per colour. Each colour component is stored in a 16-bit word, with 6
+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</para>

+ <para>Each cell is one byte, high 6 bits in high bytes are 0.
