1.1       root        1: Comments about CLOCK
                      2: 
                      3: The program illustrates various Gpi calls.  It starts a timer
                      4: which sends it WM_TIMER messages once per second.  DosGetDateTime
                      5: returns the system time.  The various graphical parts of the clock
                      6: face (face, hour hand, minute hand, second hand, major ticks, minor
                      7: ticks), are each drawn by setting the model transform and then
                      8: drawing the part in an unchanging location in world space.  Once per
                      9: minute, the clock is drawn from scratch.  The second hand is drawn
                     10: in XOR mode, so it can be redrawn in its old location (effectively
                     11: erasing it) and then drawn in its new location, without requiring
                     12: that the whole clock be redrawn.
                     13: 
                     14: Under "Preferences", if you select "Hide Frame Controls", all windows
                     15: but the client window and the size border disappear.  You can
                     16: restore them by double-clicking on the clock window, or by typing
                     17: any keyboard character when the clock window has the focus.
