Wallpaper is retrieved through the standard Android API call (WallpaperManager.getWallpaper() or something like that IIRC). We then scale it to fill the screen (cropping excess).
I've found it tends to look identical to the center screen in portrait orientations (which is what was desired). In landscape orientations the Android home screen (Eclair/Froyo/GB) seems to show the TOP portion of the wallpaper rather than the center. I think Honeycomb corrects this bug. FX displays the center in both landscape and portrait.
