dixLookupWindow uses dixLookupDrawable internally, which returns
BadMatch when the XID matches a non-Window drawable. Users
of dixLookupWindow don't care about this, just that it's not
a valid Window.
This is a generalised version of the fix for X.Org Bug 23562,
where GetProperty was incorrectly returning BadMatch. Auditing other
window requests, all that I checked would incorrectly return BadMatch
in these circumstances. An incomplete list of calls that could
incorrectly return BadMatch is: ListProperties, SetSelectionOwner,
{Destroy,Map,Unmap}{,Sub}Window.
None of the callers of dixLookupWindow, except for GetProperty, check
for BadMatch

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
