/**
 * Sigma.js WebGL Renderer Edge Program
 * =====================================
 *
 * Program rendering edges as thick lines but with a twist: the end of edge
 * does not sit in the middle of target node but instead stays by some margin.
 *
 * This is useful when combined with arrows to draw directed edges.
