/**
* This class connects KoShapeAnchor to an inline character in the text document.
*
* This class is used when the shape anchor is of type: as-char
*
* It has to be registered to the inlineobjectmanager and thus forms the connection between the text
* and the KoShapeAnchor and by extension the so called 'anchored-shape' (any kind of shape)
*
* The KoAnchorInlineObject is placed as a character in text. As such it will move and be
* editable like any other character, including deletion.
*
* Since this is a real character it will be positioned by the textlayout engine and anything that
* will change the position of the text will thus also change the KoAnchorInlineObject character.
*
* The anchored-shape can be repositioned on the canvas if the text is relayouted (for example after
* editing the text. This is dependent on how the text layout is implemented.
*
* Steps to use a KoAnchorInlineObject are
* <ol>
* <li> Create KoShapeAnchor *anchor = new KoShapeAnchor(shape);
* <li> Use anchor->loadOdf() to load additional attributes like the "text:anchor-type"
* <li> if type is as-char create KoAnchorInlineObject *anchorObj = new KoAnchorInlineObject(anchor);
* </ol>
