that get their position defined by an anchor in the text; the character (anchor)
moves, then so does the shape.
This implementation aims to be a lot broader in scope than the one in KOffce1.
We now have horizontal and vertical alignments.  So a shape can always stay
left or right of the paragraph the marker is in.  Or always top or bottom of
frame / paragraph / line.
As well as a specified distance from the anchor-character.
