The reason for the object being its own parent can be seen with the example


octave:1> hold on; hg1 = hggroup(), newplot (); hg2 = hggroup ()
hg1 = -2.3944
hg2 = -2.3944

Clearly hg1 and hg2 should be different as the hold is on and the 
newplot should add objects to the current axes.

octave:1> hold on
octave:2> get(gcf(),"nextplot")
ans = add
octave:3> get(gca(),"nextplot")
ans = replace
octave:4> hold off
octave:5> get(gcf(),"nextplot")
ans = replace
octave:6> get(gca(),"nextplot")
ans = replace

The problem is that "hold on" with no figures existing should create the 
currentaxes for the new figure. I have a few other problems I'd like to 
fix, so I'll sent changeset soon with all my fixes.
