The hint with "changes the model-view matrix" made me thinking again about my fundamental understanding of glRotate and glTranslate. So i looked up again the API spec from OpenGL 2.1 .... and there it says:
glRotate — multiply the current matrix by a rotation matrix
glTranslate — multiply the current matrix by a translation matrix
So even those fundamental commands do actually multiplications .... somehow i understand it a bit more now ....
