Log Message:
Note update of plplot to 5.0.4.

Important Changes:

(1) Default orientation for the ljii, ljiip, psc, ps, and pstex drivers has
been rotated from seascape (upside-down landscape) by 180 deg to landscape.
With this change no special 180 deg latex rotations will be required to get
true landscape mode (top of the plot on the left of the page as opposed to
on the right of the page for seascape mode).  If you still require seascape
for some reason for these drivers, use the -ori 2. command-line option or
else use plsdiori(2.) or plsetopt("ori", "2.").

(2) The installation location for examples has been changed to
$prefix/lib/plplot<ver>/examples to be in better conformance with the FHS.

Important Bug fixes:

(1) Many improvements to the octave front end.

(2) Many improvements to the xfig driver.

(3) If the overall aspect ratio is changed by the -geometry, -a, or -portrait
options or else by the combination of the -ori 1 and -freeaspect options, the
character aspect ratio remains unaffected.  For example, when the overall
aspect ratio is changed now, circular symbols remain circular rather than
turning into ellipses as in the old code.

(4) Software pattern fills now rotate correctly with the rest of the plot
when the -ori option is used.  This fix affects all drivers (e.g., xwin,
psc) which do not handle their own pattern fills.  (Previously the rotation
angle for software pattern fills was mistakenly doubled by two calls to the
orientation transformation routine.)

Important New Features:

(1) Portrait mode.  Use the -portrait option on the command line or else
plsetopt("portrait", "") to get this option which only currently affects the
ljii, ljiip, ps, psc, and pstex drivers.  This option is especially useful
for yplot, the yorick front-end to PLplot.  yplot previously maintained
separate (==> hard-to-maintain and buggy) portrait versions of the psc, ps,
and ljiip drivers.  Those will no longer be necessary with this PLplot
core change, and in fact portrait mode is now available for a much wider
range of drivers.

(2) -drvopt command-line option (or else use plsetopt("drvopt","option")).
This allows setting options for particular drivers.  For example, the
-drvopt text option for the psc or ps driver allows use of Adobe fonts (This
is poorly documented currently, but for now see notes in ps.c for more
details).

(3) New pstex driver.  This is not currently documented, but there is post
from Joćo Cardoso on plplot_devel
(http://www.geocrawler.com/archives/3/10834/2001/4/50/5536095/) that gives
the recipe (ignore the configuration stuff and start with the ./x01c
command).  The idea is to emulate the pstex output of the xfig application
so that latex can be used to directly process the file output from the
PLplot pstex driver.
