Known Problems
- If two or more images are open then drawn lines are not displayed properly.
For reasons currently unknown the points in the polyline are displayed correctly but the
connecting lines are shifted upwards.
- Due to a quirk in the cascading property of the multiple document interface in
Qt, if this is selected from the window menu then all the
currently open images are cascaded but only display their title bars. By slightly dragging
a corner of the image it pops back to its original size.
