Oops. I built the documentation but somehow missed this. I'll fix it.

Yes.
I'll also replace _packed-rgb by _pixfmt-rgb and remove the oddly-placed
"_rgb-formats:" line in what becomes pixfmt-rgb.rst, and change the
references.

The raw Bayer formats are used by image sensors before much if any processing is
performed on the image. The formats contain green, red and blue components, with
alternating lines of red and green, and blue and green pixels in different
orders. See also `the Wikipedia article on Bayer filter
<https://en.wikipedia.org/wiki/Bayer_filter>`__.

> > +These formats are designed to match the pixel formats of typical PC

> > +These are all packed-pixel formats, meaning all the data for a pixel lie
> > +next to each other in memory.
