GIMP-style docks

[Rob Adams <readams readams net>]

The GIMP dock windows don't match up well with any of the defined
semantic types in the EWHM.  Calling them UTILITY windows is a stretch
since they're potentially really big windows that do a heck of a lot
more than a little utility window or palette is supposed to do, but
they're not NORMAL either, since they are these sort of satellite
windows off to the side.

The Gimp developers and I are somewhat at a loss for the best way for
them to proceed in terms of the hints that they set on these dock
windows.  Do we need a new semantic type in the spec, or can someone
recommend a good solution with the current spec?  Or is GIMP just so
weird that we should all throw up our hands in frustration?
