## 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);
