FL_RGB and FL_SINGLE have a value of zero, so they
are "on" unless you give FL_INDEX or FL_DOUBLE.

If the desired combination cannot be done, FLTK will try turning off
FL_MULTISAMPLE. If this also fails the show() will call
Fl::error() and not show the window. </P>
<P>You can change the mode while the window is displayed. This is most
Fl::error() and not show the window.
You can change the mode while the window is displayed. This is most
useful for turning double-buffering on and off. Under X this will
cause the old X window to be destroyed and a new one to be created. If
this is a top-level window this will unfortunately also cause the
window to blink, raise to the top, and be de-iconized, and the xid()
will change, possibly breaking other code. It is best to make the GL
window a child of another window if you wish to do this!
mode() must not be called within draw() since it
changes the current context.
