Support edge labels #135

Open JanKoehnlein opened 7 years ago

Edges should have labels.

[ ] allow labels on edges in the smodel. I'd store the position as a value between 0 (source) and 1 (target)
[ ] views for labels. I prefer them to be aligned tangential to the line, i.e. rotate the text such that it goes into the same direction as the line like in FXDiagram.
[ ] move behavior: move the label along the line (see FXDiagram)

We need to extend the RenderingContext such that a view can see whether it's a hidden or normal rendering. Labels must not be rotated in hidden rendering because we need the unrotated bounds in order to compute a proper SVG transform.
