[swfmill] Define Shape?

[Christopher Simon]

Hello,

due some researches about swfmill, i converted some swf files to swfml. 
Although i found this code snipped:

DefineShape objectID="2">
         <bounds>
           <Rectangle left="0" right="14800" top="0" bottom="8800"/>
         </bounds>
         <styles>
           <StyleList>
             <fillStyles>
               <ClippedBitmap2 objectID="1">
                 <matrix>
                   <Transform scaleX="20.00000000000000" 
scaleY="20.00000000000000" transX="0" transY="0"/>
                 </matrix>
               </ClippedBitmap2>
             </fillStyles>
             <lineStyles/>
           </StyleList>
         </styles>
         <shapes>
           <Shape>
             <edges>
               <ShapeSetup x="14800" y="8800" fillStyle1="1"/>
               <LineTo x="-14800" y="0"/>
               <LineTo x="0" y="-8800"/>
               <LineTo x="14800" y="0"/>
               <LineTo x="0" y="8800"/>
               <ShapeSetup/>
             </edges>
           </Shape>
         </shapes>
       </DefineShape>

As i can imagine, this defines a Rectangle, but what else? I didn't find 
something about it in the documentation, except the parameters.

I would be glad if someone can help me.
