NAME
     glutVisibilityFunc -- Sets the Visibility callback for the current window.

LIBRARY
     OpenGLUT - deprecated

SYNOPSIS
     #include <openglut.h>

     void
     glutVisibilityFunc(void( *callback )( int status ));

PARAMETERS
      callback	   Client hook for visibility changes.

DESCRIPTION
     OpenGLUT may call this function when your window's visbility status has changed.	status	can take on two values:  GLUT_NOT_VISIBLE  or
     GLUT_VISIBLE  .  If any pixel of your window (including descendants) is visible, your window is  GLUT_VISIBLE  .

     The callback is bound to the  current window  .

CAVEATS
     This is not a polling mechanism.  You are only informed of transitions that OpenGLUT observes while your callback is in place.

     This function appears to be superceded by glutWindowStatusFunc().

     This callback is mutually exclusive of glutWindowStatusFunc().
