Through mvideowidgetview.cpp I found that you can grab the entire window 
id (which mvideowidgetview does for fullscreen) using:

         WId id = 
MApplication::activeApplicationWindow()->viewport()->winId();

I was able to do some simple tests writing to a portion of the 
MApplication screen this way by using gst_x_overlay_set_render_rectangle().
There really isn't a sub-window with mvideowidget, at least not at the 
X-window level.

I haven't studied it in detail, but I believe to do a subwindow portion, 
MVideoWidget is actually do a software frame-by-frame paint to the "sub 
window". Someone correct me if I'm stating that wrong.
