John/others,

Regarding keeping track of changes in a figures "position" property,  
I'd like to propose a solution. (1) create a new function that stores  
property info which can be later referenced by the object's handle,  
(2) have gnuplot_drawnow compare the current figure's position  
property with the prior one and reposition the figure if the property  
has changed.

I've attached a changeset for comment/discussion.

If this proposal is acceptable, should such a function be made private  
to the functions in scripts/plot ?

Ben
