Details:

In Octave 4.2.0, using the qt graphics toolkit, the coordinates that are
displayed at the bottom of a plot are wrong when a text annotation is inserted
(using the menu or the annotation() function).

The coordinates are wrongly normalized within [0, 1].

Note this issue does not exist with the fltk toolkit.

To reproduce:

graphics_toolkit('qt');

% Plot a sinus ; the display coordinates are OK
close all; clear all; x=[0:0.01:2*pi]; y=sin(x); plot(x,y);

% Annotate the figure - the display coordinates are wrongly between 0 and 1
annotation("textbox",[0.5 0.5 0 0],"string","TEXT")
