Tatsuro,

My goal was only to change Octave to require a minimum version of gnuplot 4.4.

What you propose sounds good, but also less like a bug fix and more like a
feature request.  It would be nice if Octave took advantage of the
additional capabilities of wxt that were introduced in 4.6.4.  Why don't
you file a Feature Request on Savannah for this.  The implementation should
be simple, add another feature in __gnuplot_has_feature__ and then check
for it in __gnuplot_drawnow__ to see if the positioning code can be used. 
If you or someone else uploads a changeset there is still time to get this
feature in for the 4.2.0 release.
