(un)set mouse, x11 persist and gplt_x11.c: MOUSE_ALL_WINDOWS

[Petr M. <mi...@ph...>]

According to the bug report "[ 921033 ] pipe+mouse+x11", the following
commands

set mouse
set term x11 1 persist
plot sin(x)
set term x11 2 persist
plot x
set term x11 3 persist
plot tan(x)
quit

let terminals 1 and 2 mouseable, while not 3. There seems to be a bug that
does not notify terminal 3 to be active for post-quit mousing.

Further,

set mouse
set term x11 1 persist
plot sin(x)
set term x11 2 persist
plot x
set term x11 3 persist
plot tan(x)
unset mouse

unsets mouse only in terminal 3, and not in all terminals. Also a bug.


Actually, I thought that mousing is stopped when quitting gnuplot: this
feature was available in 1998--1999 in OS/2 and later in X11, then removed
due to mousing implementation rewrite. Well, now it is back in X11 -- so,
let's keep it there, but then I think gplt_x11.c should react to "m" hotkey
to switch the mousing bar on/off.

Can somebody fix these things?

Finally, there is some funny behaviour of mousing ruler, when "set x11
<another>; replot" -- it would be nicer to position the ruler to its x,y
coordinates.
