  # A device context is used to maintain the state of the graphics drawing system.
  # Defining your drawing code in terms of the Abstract Device Context allows the
  # drawing commands to be rendered on different types of surfaces, such as windows
  # and images (FXDCWindow), or on paper (FXDCPrint).
  # WYSYWYG may be obtained by using the same identical drawing code in your
  # application regardless of the actual device surface being utilized.

    # When you call #clipChildren with the argument +true+, anything that you
    # draw into this window will be clipped by its child windows. In other words,
    # the child windows "obscure" the parent window. This is the default behavior.
    # If you call #clipChildren with +false+, anything that you draw into this
    # window will be visible in its child windows (i.e. the drawing will *not*
    # be clipped).
    #
    # === Parameters:
    #
    # +yes+::	if +true+, drawing is clipped against child windows [Boolean]
    #
