Edge arrowheads should be hidden when mouse is not over #655

Open clemsos opened 8 years ago

From W3 spec, SVG markers can not listen to mouse events : ""Event attributes and event listeners attached to the contents of a 'marker' element are not processed; only the rendering aspects of 'marker' elements are processed."

Before having stroke width as an option, the arrow size was linked to stroke width. The hiding / showing of the arrow was sort of a bug (it was hidden when not mouseover because stroke-width was =1) but now we can not do that anymore with bigger stroke width.

We have to come up with another approach to hide arrowheads.

Maybe if we used tapered edges it would be: (a) more esthetic and efficient (b) wouldn't need to hide edges in general. (c) can be of changing width.
