In Wayland, drawing is all done by the client.  This would be a function of the toolkit that you are using, say GTK or Qt.  This is how you get those boxes now.  It would not require a new mechanism in the protocol, nor does it require a new mechanism in the X11 protocol.  It is simply a slightly different application of Window.

We do not yet have stable releases of those toolkits that use Wayland as the drawing engine, but they are in process.  Be patient for a short while and your prayers will be answered.
