Just a noop that is better than crashing in the case this is called
(it can be called for a toplevel GtkWindow that is parented into
another widget by setting gtk_widget_set_parent_window to an offscreen
window).
constructors which take an object of the same class as its first argument are
mis-detected as method call with "self" argument by the GIR scanner. Using the
new (constructor) annotation from bug 561264, mark some of them as proper
constuctors, so that you can call them with NULL as first argument from
bindings; in particular, this fixes gdk_window_new() and the
gtk_radio_button_new_with*() constructors.
The previous function gdk_drag_get_protocol_for_display() took native
window handles, so it had to be changed. Because it didn't do what it
was named to do (it didn't return a protocol even though it was named
get_protocol) and because it doesn't operate on the display anymore but
on the actual window, it's now called gdk_window_get_drag_protocol().
... and all APIs making use of it.
That code like it hasn't been touched in years, Google codesearch
didn't find any users and most importantly it's a horrendous API, so
let's just make it die instead of having to port it over to
non-GdkNativeWindow usage, which would be required for multi-backend
GDK.

Use GdkWindow instead. This requires calling
gdk_x11_window_foreign_new_for_display(), so might cause a slight
performance penalty, but is required to be portable.
Only master devices must modify the associated device to separate
a pointer/keyboard pair, slave devices must only call
_gdk_device_remove_slave().
Fixes bug 639767 - password not accepted in gnome-screensaver dialog,
reported by Frederic Crozat. On VT-switch, the X server removes its
grab on HW devices, the effect on clients is that slave devices
disappear, and these were mistakenly mangling the master device
hierarchy. so gdk_device_get_associated_device() on the client
pointer wouldn't return the paired keyboard anymore.
The final effect is that gtkplug-x11 wasn't setting a keyboard to
its generated events.
slave devices don't have coordinates themselves, as they depend
on a master, this only changes if they have a grab in effect,
so only keep toplevel tracking enabled in such situation. Fixes
Bug #640313 - BadDevice X error when ungrabbing a SLAVE device,
noticed by Jesse van den Kieboom.
This function allocates the button mask, so free it after
use, or right before the next XIQueryPointer() call, as done
in gdk_x11_device_xi2_window_at_position().
mods_state->effective is not being set in XIQueryPointer() currently, so
use base|latched|locked instead, effective is nothing else than a shorthand
for these ORs, and these 3 values are set correctly anytime.
