 The other way is to provide a stripped-down version of x11 backend
 and its sole role is to connect drawing to any given xwindow.
 It's like a highway between drawing in AppKit and xwindow.
 Applications can load it as bundle and it will override most of the XGServer
 methods regarding to NSWindow.
 Anyway, I haven't find another way to go around.
 It is just a thought occured to me.
