Maybe I didn't look hard enough, but the docs don't explain a lot about the
+UA switch and how the alpha output is controlled by the absence of
background. In fact I could use that feature because I remembered it being
discussed in the newsgroups, but it doesn't seem fully documented (see
5.2.2.3.1).

if these are about what you mean, I'll add it to the docs.

Yes, that's it, it's just that these are users' knowledge of what's going on
and I was wondering whether there was an "official" description of the
behaviour.

I'm not aware of any "official" description, but after re-reading the pre-
beta discussions on the matter, the mentioned articles reflect the results 
of these discussions.
