Enable hover on parallel edges

[vigorouscoding]

If you copy the example file into the sigma.js master you will see that only the first edge will be highlighted because the node count (for parallel edges) is not used.

Hello @vigorouscoding. I am not sure to understand the way your commits fix the problem. Why do you pass an edge count to functions that do not take it? Did you forget other changes in your commit somehow?

[vigorouscoding]

Hello @Yomguithereal. The original functions reside in src/utils/sigma.utils.js and are overwritten by plugins/sigma.renderers.parallelEdges/utils.js.
For each function an extra parameter is added:
* @param {number} a Modifier for the amplitude of the curve.
and
* @param {number} a Modifier to the loop size.

So basically I just looked at code in plugins/sigma.renderers.parallelEdges/sigma.canvas.edges.curvedArrow.js where I saw the following code and made the small change at the correct place in the src/misc/sigma.misc.bindEvents.js.

    cp = (source.id === target.id) ?
      sigma.utils.getSelfLoopControlPoints(sX, sY, tSize, count) :
      sigma.utils.getQuadraticControlPoint(sX, sY, tX, tY, count);

I hope this explanation is not too convoluted.

any news on this? can I do anything to further explain my changes?

Thanks for this PR, even though it hasn't been merged.

For a few years, we focused on Sigma.js v2, and this week we released it!
It is probably better now to upgrade to this new version as v1 will no longer be maintained.

This PR will therefore be closed.
