Basic Question About Matrix Stack

Suppose this is the Display function for a very simple OpenGL, GLUT, program.

How many matrices would this put on the matrix stack?

I used to think it would be 4. However, now I'm leaning towards 1,

which would be the product of the (Identity matrix) x (the Translation Matrix) x

(the Rotation matrix) x (the Scale Matrix).

Code :

[FONT=Courier New]void Display (void)
{
glMatrixModel (GL_MODELVIEW);
glLoadIdentity ();
glTranslatef (5,3,1);
glRotatef (30, 1,0,0);
glScalef (2.1, 1.0, 2.1);
glBegin (GL_POINTS);
glVertex2d (5,2);
glEnd ();
}[/FONT]

Thanx.
