* overlap.c:150: (yath: falschrum?)
   if (label.top > b.bottom || label.bottom < b.top) return(0);

14:39 <yath> Myon: ich hab ne alternative berechnung für overlap.c
14:39 <yath> overlapX = abs(min(one["right"], two["right"]) - max(one["left"], two["left"]))
14:39 <yath> overlapY = abs(max(one["bottom"], two["bottom"]) - min(one["top"], two["top"]))
14:40 <yath> Myon: top/bottom wird von unten gezählt, left/right von links

* draw links per marker, not per key
* adapt pisg's addalias.pl
* labels with negative coordinates like -geometry
  use upper left corner for positive values
* view_* in pixels
* coordinates wraparound (i.e. not necessary to replace -20 by 340)
