investigate vector pointer areas

[pixelzoom]

Related to #205, review pointer areas...

These are some strange looking pointer areas, in vector creator panels (toolboxes):

And these look at bit suspicious too, on the graph:

If I increase the pointer area dilations for vectors on the graph, they look like the vectors in the toolbox, see below.

The pointer areas are set like this in RootVectorNode:

this.arrowNode.mouseArea = this.arrowNode.shape.getOffsetShape( ARROW_MOUSE_AREA_OFFSET );
this.arrowNode.touchArea = this.arrowNode.shape.getOffsetShape( ARROW_TOUCH_AREA_OFFSET );

So maybe this is just how things look when using ArrowNode's shape.

@jonathanolson do you see anything odd here, or is this expected behavior?

[jonathanolson]

The code to make offset shapes would make those expected results. Are you asking whether those are the shapes we want? Or if there is a technical issue in that the shapes are unexpected?

[pixelzoom]

Thanks. I was asking whether that's the expected result, given the current implementation. It's working fine, so no technical issues. But I was expecting to see something like this:

Versus what the current implementation does:

EDIT: The latter looks like there are separate pointer areas for the arrow's tail and head.
