[MPlayer-dev-eng] vo_xmga - set_window() question

[Attila Kinali]

Hi,

I'm trying to get vo_xmga Xinerama aware.

I looked a bit deeper into the code of vo_xmga and found following
lines from set_vindow() 

---schnipp---
 XGetGeometry( mDisplay,mWindow,&mRoot,&drwX,&drwY,&drwWidth,\
               &drwHeight,&drwBorderWidth,&drwDepth );
         drwX=0; drwY=0; // drwWidth=wndWidth; drwHeight=wndHeight;
         XTranslateCoordinates( mDisplay,mWindow,mRoot,0,0,&drwcX,&drwcY,&mRoot);
---schnapp---

What is the sense behind getting drwX and drwY with XGetGeometry and
clearing them right after ?
And why is XTranslateCoordinates() used ?


Thanks for helping
