On X11, sends an X ClientMessage event to all toplevel windows on
<em class="parameter"><code>screen</code></em>. 
</p>
<p>
Toplevel windows are determined by checking for the WM_STATE property, 
as described in the Inter-Client Communication Conventions Manual (ICCCM).
If no windows are found with the WM_STATE property set, the message is 
sent to all children of the root window.
</p>
<p>
On Windows, broadcasts a message registered with the name
GDK_WIN32_CLIENT_MESSAGE to all top-level windows. The amount of
data is limited to one long, i.e. four bytes.</p>
