Begin a new sub-path. After this call the current point will offset by rp1.
Given a current point of (x, y), cairo_rel_move_to(cr, dx, dy) is logically equivalent to cairo_move_to(cr, x + dx, y + dy).
It is an error to call this function with no current point. Doing so will cause an CairoException with a status of CAIRO_STATUS_NO_CURRENT_POINT.
