Follow-up Comment #8, bug #51452 (project octave):

Matlab is being dopey here.  In terms of the philosophy of UI design, I should
not expect that there would be side effects from calling ginput.  It would be
more intuitive if ginput were to save the current graphics settings, execute,
and then restore the settings.  I see no need to slavishly copy Matlab in this

At least for the FLTK toolkit this may not be hard to implement.  The menu
options are already implemented as uimenus if we want to disable them.  And
the actual zoom, pan, rotate values are stored in hidden properties on the
figure (__rotate_mode__, __pan_mode__, __zoom_mode__).  The ginput.m script
already uses an unwind_protect block to restore some settings after
completion.  It should be dead simple to store and retrieve these values.
