I don't consider it a top priority, and given there I have lots of other
things to do I most likely wouldn't implement that.  But I wouldn't
object if someone comes up with a sane implementation.

What we have right now is just a big mess though, both in code and the
user interface.  First, these are toplevel command line options.  It
belongs to -display though.  Second, it's two hard-coded names for two
hard-coded variations.  So it's not like you can configure much.  On top
of that the names are not exactly intuitive.  And it works with SDL only.
