Actually, this will not place it in the middle, it will place its upper border
in the middle. 0 should be used instead of 384. Nevermind, the problem is
elsewhere...

Yes and no.

Your solution does the right thing, but uses software scaling, which is
something I would like to prevent.

Obviously, I would welcome something like the -2, but as an argument to expand.
Should I cook up a patch for this, or is something similar flying around (or in
CVS, for example)?

Please, CC me on replies. Thanks.
