glLoadIdentity - replace the current matrix with the
identity matrix

glLoadIdentity
	glLoadIdentity() -> None

void glLoadIdentity( void )

glLoadIdentity replaces the current matrix with the identity
matrix.  It is semantically equivalent to calling
glLoadMatrix with the	identity matrix

                     ( 1   0	 0   0	)
                     |                |
                     | 0   1	 0   0	|
                     | 0   0	 1   0	|
                     |                |
                     ( 0   0	 0   1	)

but in some cases it is more efficient.

GL_INVALID_OPERATION is generated if glLoadIdentity is
executed between the execution of glBegin and	the
corresponding	execution of glEnd.
