For X specifics there's either an oldish X11::Lib calling xlib, or a
newish X11::Protocol directly speaking X.

You can open a second server connection and use XID's from gtk/gdk stuff
on that second connection, if you're really keen.  I used X11::Protocol
for an XQueryTree to find the window manager frame window, which gdk
otherwise pretends doesn't exist.
