I have intentions of starting work on the GTK backend again soon, and am 
wondering if it makes sense to extract a bunch of the functionality that is 
already present in the FLTK backend (big thanks to everyone who has implemented 
that) and put the common functionality in either a backend base class or a 
backend helper class.  The functions I am thinking about are things like:

I will probably end up just copying a bunch of these anyway and use your FLTK 
event handler as a template for the right way to interact with the Octave 
graphics properties.
