+// show() of any windows.  Mesa will crash if you try to use a visual

+// not returned by glxChooseVisual.

+

+// This does not work with Fl_Double_Window's!  It will try to draw

+// into the front buffer.  Depending on the system this will either

+// crash or do nothing (when pixmaps are being used as back buffer

+// and GL is being done by hardware), work correctly (when GL is done

+// with software, such as Mesa), or draw into the front buffer and

+// be erased when the buffers are swapped (when double buffer hardware
