[gnuplot-beta]metapost terminal

[Ethan A M. <merritt@u.washington.edu>]

Thanks to Andrzej W=C4=85sowski and Dan Luecking, I now know how to=20
run the output of 'set term mp' through mpost + latex + dvips to see
what it is doing.

With their guidance I have patched the terminal to support text rotation
and filled boxes.  I do not know how to add pattern-fill, but for the mom=
ent
I have dummied it up with different solid fill densities.

However, I notice that the line colors and point styles do not match
those of other terminal types.  We changed many (though not all)
terminals a year ago to match each other as closely as possible at
least for the first 8 line colors and first 12 point styles. In particula=
r,
almost all terminals supporting color assign  linetypes 1, 2, 3 to be
red, green, blue. Metapost uses instead black, red, blue.

While I can see the logic behind having "lt 1" produce a black line,
the other terminal types don't do it that way. Instead, all terminal type=
s
that I know of provide black (or at least "foreground") as linetype -1.

Should I re-order the line and point types in the metapost driver to
match other drivers? =20
