流程管理工具JBPM的jpdl.xml文件里 g=后面的数字是什么意思？

[xianjijida7217]

    <process name="decisionsUsingTransitions" xmlns="http://jbpm.org/4.0/jpdl">
       <start g="72,168,48,48" name="Start">
          <transition to="Decision"/>
       </start>
       <decision expr="#{opcao}" g="192,168,48,48" name="Decision">
          <transition g="217,84:23,-21" name="Opção A" to="Opção A"/>
          <transition g="-26,-20" name="Opção B" to="Opção B"/>
          <transition g="217,302:22,5" name="Opção C" to="Opção C"/>
       </decision>

上面的xml文件里
诸如192,168,48,48是什么意思？

应该和位置有关系， 这个配置文件不是可以自己手动拖动。
