- * !!! NOTE !!!

- * This demo is poorly written.  The stencil buffer should be
- * redrawn in display(), not in the myReshape() function.
- * The reason is if the window gets "damaged" then the stencil buffer
- * contents will be in an undefined state (myReshape is not called when
- * a window is damaged and needs to be redrawn).  If the stencil buffer
- * contents are undefined, the results of display() are unpredictable.
