I agree, given the sheer number of these rarely used pixel formats, I
suppose it's not worth the extra code complexity to add them all in.

If we are keen on having support for these pixel formats, I think it
would make more sense to have a way for users to specify custom
formats? But even then I don't know how useful that would be for most
people.

In the meantime, I'll remove the new format from the patch.
