My bad, I only had a look at RGB formats.
I'll fix that.

If you take a look elsewhere in the header, you'll notice that the
ordering has preferred the BPP value (and other values with semantic
significance) over the numeric value of the definition. I'd just prefer
to keep it that way. This is also why the "next is" comments are there.

I cannot keep both macro values and BPP/bits per sample in incrementing
order. Are you sure you prefer to order macros in BPP/bits per sample
order ?

I'd arrange these according to BPP and bits per sample, both in the header
and documentation.
