NAME
     glutWarpPointer -- Moves the mouse pointer to given window coordinates.

LIBRARY
     OpenGLUT - window

SYNOPSIS
     #include <openglut.h>

     void
     glutWarpPointer(int x, int y);

PARAMETERS
      x 	Window X coord for mouse.

      y 	Window Y coord for mouse.

DESCRIPTION
     glutWarpPointer() moves the mouse pointer to window-relative coordinates given by	x  and	y.

CAVEATS
      x  and  y  are relative to current window.

     Not applicable for  GLUT_OFFSCREEN  windows.

     Warping means moving, just as if the user had manually moved the mouse.  This can generate mouse-motion callbacks. If your callback then
     moves the pointer again, you may end up in an endless loop.  There is some discussion about changing this, but at present this is just a
     caveat for you, the user, to be aware of.
