For some reason, hopefully trivial to find, the annotation command displays a blank window if the existing figure doesn't have an axes object.

Code to reproduce:

A new figure is created, and h holds a graphics object handle, but nothing is displayed. By contrast, Qt works.

It is enough to add an axes to have this work

The issue seems to be that when there is no handlevisible, axes object below the figure Octave believes that nothing needs to be drawn.
