Either normalizes given gradient to vector, or returns fresh normalized vector - in latter case, original gradient is flattened and stops cleared.

No transrefing - i.e. caller shouldn't hold reference to original and does not get one to new automatically (doc holds ref of every object anyways)

	)

Set the position of point point_type of the gradient applied to item (either fill_or_stroke) to p_w (in desktop coordinates).

Write_repr if you want the change to become permanent.
