/* beginpath:
 * Set up boxes near the tail node.
 * For regular nodes, the result should be a list of contiguous rectangles 
 * such that the last one has the smallest LL.y and its LL.y is above
 * the bottom of the rank (rank.ht1).
 * 
 * For flat edges, we assume endp->sidemask has been set. For regular
 * edges, we set this, but it doesn't appear to be needed any more.
 * 
 * In many cases, we tweak the x or y coordinate of P->start.p by 1.
 * This is because of a problem in the path routing code. If the starting
 * point actually lies on the polygon, in some cases, the router gets
 * confused and routes the path outside the polygon. So, the offset ensures
 * the starting point is in the polygon.
 *
 * FIX: Creating the initial boxes only really works for rankdir=TB and
 * rankdir=LR. For the others, we rely on compassPort flipping the side
 * and then assume that the node shape has top-bottom symmetry. Since we
 * at present only put compass points on the bounding box, this works.
 * If we attempt to implement compass points on actual node perimeters,
 * something major will probably be necessary. Doing the coordinate
 * flip (postprocess) before spline routing will be too disruptive. The
 * correct solution is probably to have beginpath/endpath create the
 * boxes assuming an inverted node. Note that compassPort already does
 * some flipping. Even better would be to allow the *_path function
 * to provide a polygon.
 *
 * The extra space provided by FUDGE-2 prevents the edge from getting
 * too close the side of the node.
