LIBRARY
     OpenGLUT - window

SYNOPSIS
     #include <openglut.h>

     void
     glutPostRedisplay(void);

DESCRIPTION
     Whenever circumstances indicate that your window is in need of being redisplayed, you may call glutPostRedisplay() to tell OpenGLUT that you
     want to redraw your graphics.  Multiple calls to this function may be coalesced by OpenGLUT to avoid excessive invocation of your drawing
     support.

     The ultimate effect of this function is to call your Display callback for the  current window  .
