Bug#668956: gnuplot-x11: With the 'qt' terminal, the initial window size is incorrect

[Vincent Lefevre]

Package: gnuplot-x11
Version: 4.6.0-5
Severity: normal

With the 'qt' terminal, the initial window size is incorrect.
This can be seen with fvwm's active placement (because the frame
of the initial window is displayed until the window is placed by
the user). The can also probably be visible with xtrace.

The consequences are the following if the window manager places the
window depending on its initial size:
  * The window can be partly off-screen.
  * The window can cover other windows (in particular the one that
    is used to run gnuplot from a shell), even though there is
    enough empty space for it elsewhere.
I could reproduce both problems on my machine.

The testcase:

$ gnuplot -persist <<EOF
plot '-' using 1:2 t '' with line
0 0
10 10
e
EOF

There is no such problem if one uses "set terminal wxt".
