  The mask is easily constructed using an Fl_Image_Surface object,
  drawing white areas on a black background there, and calling Fl_Image_Surface::image().

  - The image surface must not be the current drawing surface when this function
  gets called.
  - The mask can have any size but is best when it has the size of the image surface.
  - It's possible to use several masks in succession on the same image surface provided
  member function Fl_Image_Surface::image() is called between successive calls to
  Fl_Image_Surface::mask(const Fl_RGB_Image*).

  Example of procedure to construct a masked image:
  \code
