The images-off argument is a pair filenames to be load as the
button-label image, where the first is the image for when the button
is at rest, and the second is the image for the button while its
pressed – in both cases when the button is not checked by the
user. The images-on argument similarly determines the images
for then the button is checked.
The turn-on and turn-off callbacks are invoked when the button changes to checked or unchecked, respectively.
The state argument determines whether the button is initially
checked.
