heh.. yes.. for getting devel going, a placeholder is fine. 

as marco noted, a proxy widget isn't going to be much help. what is needed is 
a QML element that knows of the top level window so it can set xatoms as 
needed (and later whatever we do for wayland, etc).

so to me it makes sense to have this particular QML item be a C++ subclass of 
QDeclarativeItem that is tightly coupled to the window implementation and has 
a property for the window id to show.

one question would be whether to support showing multiple windows in one of 
these items, or one window per item. i lean towards one window per item for 
ease of implementation and flexibility of use inside the QML.

(and yes, with the xatom approach we'll run into repaint latency issues if 
these are highly animated ... but let's start with this and then start 
experimenting from there.)
