The octave example problem is now fixed thanks to some quick work from Joao.

I have just completed a whole host of tests of various device drivers. The
png, jpeg, cgm, and plmeta devices give perfect results as far as I can see.
There are some 285 plot pages to look at for _each_ so bear with me if I
missed something minor.  There is a legend sizing problem for some of the
experimental "p" octave examples for png (and others), but that is nothing
new. I expect raw device coordinates are being used in those examples (which
will vary from device to device) rather than normalized device coordinates
or world coordinates.  I hope those "p" example legends get changed over to
some sort of normalized device coordinates so this will no longer be a
problem. However, Joao, if some sort of normalized device coordinates are
already being used, please let me know and we should follow up on this
further to see why we are getting device-dependent legend size results for
those examples.

The cgm results are particularly noteworthy in how fast they are produced,
and how nice they look afterward.  It is just a real shame that that
absolutely free (libcd is a public domain software library) format has never
gotten much mindshare in the Linux community.  I guess it just works too
easily, and people pay attention to other things that have constant
problems....;-)

Some of the poorly supported drivers look, well, poorly supported. I only
did a few spot checks for gnome, xfig, and pbm.  I noticed some rendering
problems (gnome, xfig), colour map problems (xfig), and extremely bad
resolution (pbm).  Again, however, I don't think anything new has cropped up
(i.e, the situation is not worse than 5.1.0) so I will continue.

The next step (as I said before, but I forgot how many plots I had to look
at before I could get to it), is making the rpm (which will test the install
relocatibility of the new configuration scheme).  I will start that early
tomorrow after I get some sleep.
