        !             4: 
        !             5: The sample named ANGLE provides a demonstration of how the
        !             6: new AngleArc API function works. The X, Y, and RADIUS
        !             7: parameters are all in the world coordinate space. The start
        !             8: angle and sweep angle are floating-point values and are
        !             9: interpreted as degrees.
        !            10: 
        !            11: More Information:
        !            12: 
        !            13: This program presents a dialog box stretched across the top
        !            14: of the window. The user can set the parameters for the
        !            15: AngleArc API function by changing the values in the entry
        !            16: fields of this dialog box. A button on the dialog box then
        !            17: allows the user to immediately see the results of these
        !            18: values on the arc in the client area. If the values in the
        !            19: entry field are invalid, the program will write out this
        !            20: information and not draw the arc. The origin of the viewport
        !            21: is shifted down in the client area so that it exists at the
        !            22: upper-left corner of the viewable area.
        !            23:
