Halo masking

In dense graphs it can become hard to visualize which edge is connected to which node. The halo.hideNonAdjacentEdges attribute allows a node's halo to mask edges that are not adjacent to the node.
In this example, this attribute is set to true when a node is selected. Try to select a few nodes and see what happens.

Note: this feature is only available in the WebGL renderer.
