-        Elm image	- purple shaded sky image
-        Elm box		- so everyone gets a freebie
-
-      Elm glview	- added by init_evas_gl() if this is Irrlicht
-
-      Elm image		- added by Evas_3D_Demo_add() -> scenriAdd()
-        Evas image is extracted to pass to Evas_3d functions,
-          to catch hovers and clicks
-          and to catch input for the camera
-
-//      Elm win		- added by overlay_add()
-//        Evas rectangle added, a fully transparent one to catch clicks
-//          added to  evas_object_evas_get(gld->winwin)
-
-      The various internal windows.
