       glRotate - multiply the current matrix by a rotation matrix

       void glRotated(GLdouble angle, GLdouble x, GLdouble y, GLdouble z);

       void glRotatef(GLfloat angle, GLfloat x, GLfloat y, GLfloat z);

	   Specifies the angle of rotation, in degrees.

       x, y, z
	   Specify the x, y, and z coordinates of a vector, respectively.

       glRotate produces a rotation of angle degrees around the vector x y z. The current matrix
       (see glMatrixMode()) is multiplied by a rotation matrix with the product replacing the
       current matrix, as if glMultMatrix() were called with the following matrix as its

       x 2  1 - c + c x  y  1 - c - z  s x  z  1 - c + y  s 0 y  x  1 - c + z  s y 2  1 - c + c y
       z  1 - c - x  s 0 x  z  1 - c - y  s y  z  1 - c + x  s z 2  1 - c + c 0 0 0 0 1

       Where c = cos  angle, s = sin  angle, and x y z = 1 (if not, the GL will normalize this

       If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects drawn after
       glRotate is called are rotated. Use glPushMatrix() and glPopMatrix() to save and restore
       the unrotated coordinate system.

       This rotation follows the right-hand rule, so if the vector x y z points toward the user,
       the rotation will be counterclockwise.

       GL_INVALID_OPERATION is generated if glRotate is executed between the execution of
       glBegin() and the corresponding execution of glEnd().
