Allow for an absolute (px) value for positionOnEdge

[samvloeberghs]

Currently positionOnEdge allows for a relative value (0 -> 1) to position the label on the edge.
Would it be possible to extend this and also allow an absolute (px) value.

Use case: I want to have the label always 10px next to the source node, independent from the length of the edge

Yes, it's possible for us to extend edge labels to support absolute positioning along the edge. We just need to carefully assess it and design the API. I'll keep you informed once we have a timeline for this change

@samvloeberghs, this is now available in v1.1.0.

You can now use both relative and absolute units for edge label positioning (for example 0.5 or 30px, -30px).
