I'm not very happy with this name, "4XX" notation only makes sense
when we have three components, in this case I would have preferred
something of the kind GRAY8ALPHA8 or GRAYALPHA8 (consistent with
GRAY8), even YA was not that bad.

Not that I consider this a big issue, we will eventually fix the names
at the next major bump.
