Details:

I've seen some problems regarding the gnuplot toolkit. The overall behaviour
seems very ambiguous.

Here an example:
1) Set graphics toolkit to "gnuplot"

graphics_toolkit('gnuplot')

2) Using simple plot commands, either...

plot(1:10)

or...

figure
plot(1:10)

everything works fine, the xwt terminal is used and windows shows gnuplot.exe
as executable. As long as the first figure or any subsequent figures remain
open, the terminal and the executable is unchanged.
3) Closing all opened figure windows (mouse or command) an re-open a figure
switches the terminal and the executable.

close all
figure
plot(1:10)

The figure command opens a figure in the wxt terminal, but the plot command
doesn't plot in this figure, now the gnuplot-qt.exe is opened and the plot
appears in another terminal window.

Other combinations are possible, I get up to three different terminals only
using the commands figure-plot-close in different order.
