"title" and "frame" in PostScript output

[Qian Yun]

By default, there's no "title" in PostScript output.

Simply enable "Gdraws_drawFrame" in src/graph/Gdraws/Gfun.c
will give you "title" back, along with "frame" (thin lines)
around titleWindow and viewWindow.

That's a discrepancy with the xpm format.

Also the position of "title" in PS format is higher than the xpm format.

My point is, should we try to make the PS format and xpm format
look the same?

In general, I would say yes. On the other hand what part of FriCAS is
using the xpm format? If it is only HyperDoc, then I don´t care as I do
not care much about HyperDoc at all. It is good as it is, but otherwise
ancient feeling that (in my opinion) rather drives people away than it
attracts new users.

It is better to present consitent interface. OTOH important use of
.ps is for inclusion inside text. In such case title and frame
may be undesirable. So I think we need a way to control inclusion
of title and frame.

It is definitely possible to control the inclusion, but that means
adding another global variable. Because it also affects the size of
BoundingBox.

Since this "title and frame" is not there for the past decades,
I think we can start freshly by choosing "title inside
viewWindow and no frame"?

I would not worry to much about global variable. I mean, there
are several of them already. And there is call structure passing
data between functions. I think that we can move most of global
data to function parameters. And we can add new field to
corresponding structures, so we can pass all data that is needed.

I think that we should try to preserve/expose flexibility
that is there. Ideally various options could be used in
any combination (of course, so option combinations really
do not make sense, but we should exclude only ones that
are _really_ nonsense).
