There are two methods available: Fl_Widget::image() for the image of an
active widget and deimage() for an inactive widget. There are also
several alignment options Fl_Widget::align() to position an image and
additional label text.

And if you want the button's text label() to appear
inside the image (comped 'over' it), you can add:

FL_ALIGN_IMAGE_BACKDROP

..to the align() flags. See: http://seriss.com/people/erco/fltk/#TextOverImage

This is not to be confused with the other align() flag
that might seem to mean the same thing:

FL_ALIGN_TEXT_OVER_IMAGE

..which means 'over' the image in the sense of
"above and outside" the image, i.e. along its top edge.
