1.1       root        1:  Sample: AngleArc Demonstration Program
                      2: 
                      3: Summary:
                      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: 
                     24: The following is a list of the Win32 API functions used in
                     25: this sample:
