OK. I have updated the debian patches for this release.  Mostly
straightforward, and I see the build has been made a little less
baroque in various places, which is good :-)

makeinstall.tcl changing its behaviour to use $DESTDIR and make it's
directories was a little surprise, but easily sorted and a cleaner
rules file.

I see there is now vtk9 support (since 5.5.2).  Debian has vtk9 now
(in unstable and testing). Do we get useful things for building
against vtk9 rather than vtk7?
We'd need to use vtk7 (or vtk6) in backports but as vtk is just for
the loch gui and image processing I can't see why different versions would matter.

Both vtk7 and vtk9 seem to work. I guess we should move on so I'll
move to vtk9 unless someone can think of a good reason why not.

One oddness:
samples/samples.tcl has had the catch stanza commented out in proc process_files {}
    #catch {
      eval "exec $p >&@ stdout"
#      eval exec "cmd /c $p"
    #}

What's that about? It looks like debugging that accidentally got into
the release? The effect is to prevent the samples build from
completing unless cavern is actually installed. I could make cavern a
build-dependency, but we never have before, and if I just put it back
then the samples build as usual (so that's what I've done for now).
