Use "update" method to initialize Qt Figures (cleanup + bug #46086) * Figure.cc (Figure::Figure): call "update" method on "windowbuttonmotionfcn" property to decide wether to update currentpoint and execute the function. * Figure.cc (Figure::Figure): call "update" method to avoid duplicate code for "visible", "keypresfcn" and "keyreleasefcn" properties. * Figure.cc (Figure::Figure): don't enable mouse tracking twice * Figure.cc (Figure::Figure): remove left-over debug comments

Octave works best with gnuplot 4.4 or higher, which is available from
http://www.gnuplot.info.

In versions prior to 4.2.6 it is not possible to use the mouse to zoom in
on plots.  This is a limitation of earlier versions of gnuplot, which are
unable to zoom when the data it plots is not stored in a file.
