glutInitWindowPosition,  glutInitWindowSize - set the ini-
tial window position and size respectively.

glutInitWindowPosition
	glutInitWindowPosition(x, y) -> None
glutInitWindowSize
	glutInitWindowSize(width, height) -> None

void glutInitWindowSize(int width, int height);
void glutInitWindowPosition(int x, int y);

width     Width in pixels.

height    Height in pixels.

x         Window X location in pixels.

y         Window Y location in pixels.

Windows created by glutCreateWindow will be  requested  to
be  created  with  the current initial window position and
size.

The initial value of  the  initial  window  position  GLUT
state is -1 and -1.  If either the X or Y component to the
initial window position is  negative,  the  actual  window
position  is  left to the window system to determine.  The
initial value of the initial window size GLUT state is 300
by  300.   The  initial  window  size  components  must be
greater than zero.

The intent of the initial window position and size  values
is to provide a suggestion to the window system for a win-
dow's initial size and position. The window system is  not
obligated  to  use this information.  Therefore, GLUT pro-
grams should not assume the  window  was  created  at  the
specified  size or position. A GLUT program should use the
window's reshape callback to determine the  true  size  of
the window.

If you would like your GLUT program to default to starting
at a given screen location and at a given  size,  but  you
would  also  like  to let the user override these defaults
via a command line argument (such as -geometry  for  X11),
call  glutInitWindowSize and glutInitWindowPosition before
your call to glutInit.  For example:

  int main(int argc, char **argv)
  {
    glutInitWindowSize(500, 300);
    glutInitWindowPosition(100, 100);
    glutInit(&argc, argv);
    ...
  }

However, if you'd like to force your program to  start  up
at  a given size, call glutInitWindowSize and glutInitWin-
dowPosition after your call to glutInit.  For example:

  int main(int argc, char **argv)
  {
    glutInit(&argc, argv);
    glutInitWindowSize(500, 300);
    glutInitWindowPosition(100, 100);
    ...
  }

shapeFunc, glutGet
