+ This window provides double buffering and also the ability to draw the
+ "overlay" which is another picture placed on top of the main image. The
+ overlay is designed to be a rapidly-changing but simple graphic such as
+ a mouse selection box. Fl_Overlay_Window uses the overlay
+ planes provided by your graphics hardware if they are available.
+ <P>If no hardware support is found the overlay is simulated by drawing
+ directly into the on-screen copy of the double-buffered window, and
+ "erased" by copying the backbuffer over it again. This means the
+ overlay will blink if you change the image in the window.
