Realtime overview
As the joystick moves (as long as the camera
is in live mode) an image (low resolution) is displayed on the screen.
One of the uses of this mode is to keep track of areas of the slide
that have been visited and quickly return to them (by clicking on the
low resolution image).
Load - loads an old
stage scan (useful if the software suddenly crashes).
Reset - clears the
overview image.
Disable/Enable - turns the
overview image into a real-time overview panel.
