STATIC SUB LoadIdentity ( )
Gl.LoadIdentity replaces the current matrix with the identity matrix. It is semantically equivalent to calling Gl.LoadMatrix with the identity matrix
but in some cases it is more efficient.
Gl.GL_INVALID_OPERATION is generated if Gl.LoadIdentity is called between a call to Gl.Begin and the corresponding call to Gl.End.
