How to implement vista progressbar marquee drawing?



Microsoft define some new theme element for progressbar in vista, see the following:

1. 
   
2. <Control name="PROGRESS">
   
3.       <Part name="PP_BAR" value="1" >
   
4.       </Part>
   
5.       <Part name="PP_BARVERT" value="2" >
   
6.       </Part>
   
7.       <Part name="PP_CHUNK" value="3" >
   
8.         </Part>
   
9.       <Part name="PP_CHUNKVERT" value="4" />
   
10.       <Part name="PP_FILL" value="5">
    
11.         <State name="PBFS_NORMAL" value="1" />
    
12.         <State name="PBFS_ERROR" value="2" />
    
13.         <State name="PBFS_PAUSED" value="3" />
    
14.         <State name="PBFS_PARTIAL" value="4" />
    
15.       </Part>
    
16.       <Part name="PP_FILLVERT" value="6">
    
17.         <State name="PBFVS_NORMAL" value="1" />
    
18.         <State name="PBFVS_ERROR" value="2" />
    
19.         <State name="PBFVS_PAUSED" value="3" />
    
20.         <State name="PBFVS_PARTIAL" value="4" />
    
21.       </Part>
    
22.       <Part name="PP_PULSEOVERLAY" value="7" >
    
23.         </Part>
    
24.       <Part name="PP_MOVEOVERLAY" value="8" >
    
25.       </Part>
    
26.       <Part name="PP_PULSEOVERLAYVERT" value="9" >
    
27.         </Part>
    
28.       <Part name="PP_MOVEOVERLAYVERT" value="10" ></Part>
    
29.       <Part name="PP_TRANSPARENTBAR" value="11">
    
30.         <State name="PBBS_NORMAL" value="1" />
    
31.         <State name="PBBS_PARTIAL" value="2" />
    
32.       </Part>
    
33.       <Part name="PP_TRANSPARENTBARVERT" value="12">
    
34.         <State name="PBBVS_NORMAL" value="1" />
    
35.         <State name="PBBVS_PARTIAL" value="2" />
    
36.       </Part>
    
37.     </Control>

May the Chunk, Fill, and MOVEOVERLAY is useful, see the folowing picture:



We can draw the progress bar default effect by draing Chunk + MoveOverlay.

The Marquee chunk element isn't defined directly, and  maybe the Marquee chunk seems make some transform for default chunk by MoveOverlay or other.
