Are you talking about this?
<area x="0%" y="0%" width="100%" height="100%" />
Change the settings a bit and it sounds like what you are looking for.
Michel made a great example here for resetting the area but it also shows the basic use of the <area> tag.

While he did not place any plugins outside of the <area> it can be done.
The entire window is usable to place whatever plugin you wish while the pano is separate. I believe you must use parent="STAGE" in the plugin to get the plugin outside of the selected area. Of course you can still place plugins inside the viewing area too.
