20	<para>These four pixel formats are packed raw sRGB /
21	Bayer formats with 10 bits per colour. Every four consecutive
22	colour components are packed into 5 bytes. Each of the first 4
23	bytes contain the 8 high order bits of the pixels, and the
24	fifth byte contains the two least significants bits of each
25	pixel, in the same order.</para>
26
27	<para>Each n-pixel row contains n/2 green samples and n/2 blue
28	or red samples, with alternating green-red and green-blue
29	rows. They are conventionally described as GRGR... BGBG...,
30	RGRG... GBGB..., etc. Below is an example of one of these
31	formats:</para>
