#226 Complex BPMNEdge waypoints

[Nils Leideck]

The sequence flows currently availble in Yaoqiang often cross other lines and elements, making larger diagram looking ugly and often unusable to read.

Yaoqiang should support complex BPMNEdge waypoints such as:

  <bpmndi:BPMNEdge id="SequenceFlow_18fx9n1_di" bpmnElement="SequenceFlow_18fx9n1">
    <di:waypoint xsi:type="dc:Point" x="209" y="120" />
    <di:waypoint xsi:type="dc:Point" x="245" y="120" />
    <di:waypoint xsi:type="dc:Point" x="245" y="133" />
    <di:waypoint xsi:type="dc:Point" x="281" y="133" />
    <bpmndi:BPMNLabel>
      <dc:Bounds x="260" y="116.5" width="0" height="0" />
    </bpmndi:BPMNLabel>
  </bpmndi:BPMNEdge>

This allows users / modelers to draw sequence flows around other objects, leading to much nicer diagrams, less clutter and much higher acceptance in non-technical levels.

Cheers, Nils
