patch with proposed changes

This functionality is useful when using placeholder anchor information when placing images.

(pseudo-)code example:

        // content placeholders
        LinkedList<XSLFTextShape> placeContent = ...;

        LOOP:
        {
            XSLFShape place = placeContent.poll();
            Rectangle2D anchor = place.getAnchor();
            slide.removeShape(place);

            XSLFPictureShape shape = slide.createPicture
            (
                slide.getSlideShow().addPicture
                (
                    ...
                )
            );

            shape.resize(anchor, RectAlign.TOP_RIGHT);
        }

Depends on #58207
