bugs in tikz, metapost terminals

[Allin C. <cot...@wf...>]

In the first instance I'm just wondering if these issues are on 
anyone's radar:

* The tikz terminal doesn't respect the "mono" option; it produces
a color plot regardless.

* The metapost terminal doesn't respect the "dashed" option; it uses 
solid lines regardless.

This is in both 5.0.1 and current CVS. The mp term did dashes OK in 
gnuplot 4.6.

If nobody's working on these points I can try to come up with patches.

I am traveling and cannot test old versions of gnuplot, so I do not
know if tikz mono used to work or not.   I do see that "set mono"
works fine for the tikz terminal, so that is available as an alternative.

I do not think support for the new dashed line mechanism was ever
added to the metapost terminal.

Version 5 uses a different API for dashed lines.
Terminals that do not support the new API are supposed to fall back
to the old dashed line sequence via the generic routine null_dashtype().
I do not know why that is failing for the metapost terminal.
I guess the first thing to check there is whether the fallback mechanism
is failing for all the old un-converted terminals or whether it is specific to 
mp.

I've now checked, and tikz mono used to work in 4.6.0.

This was apparently deliberate, according to a comment in
gnuplot-tikz.lua, but I do not know why setting the flag in the lua
script causes a problem.  As of today, the CVS version of the lua
terminal treats "set term tikz mono" as if there were two separate
commands: "set term tikz; set mono".  This is essentially the same as
the postscript terminal now does.

Thanks, Ethan, that sounds good.
