Yes, the Windows clipboard can handle enhanced metafiles, and
since we have a good driver for that format in emf.trm it would be
a good idea to make use of it. (I suspect -- though I admit I'm
winging it here -- that Windows could downgrade it to WMF if
needed for an archaic paste target that can't handle EMF.)

One observation on gnuplot 4.4: this list has been much taken up
with somewhat arcane problems on Windows.  My 2 cents is that it
would be good to have 4.4 out as soon as possible just so long as
there are no substantial regressions relative to 4.2 (given how
much good stuff 4.4 contains).  I fear that waiting for perfection
on "pause mouse" and company could be a recipe for indefinite
postponement.
