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.
There's no usecase for them, so remove them before we have to commit to
keeping an API.
Make the hooks private for now, actually removing them will come in
followup patches.
Its usecase was GERD - http://testbit.eu/~timj/historic/gerd/ - and that
project is long since dead.
I couldn't find any app using it after asking around and googling either.

It has been superseded in GTK 2.2 by GdkDisplayPointerHooks anyway.
We want to have different window types for different displays, so we can
write code like this:
#if GDK_WINDOWING_X11
if (GDK_IS_X11_WINDOW (window))
{
/* do x11 stuff */
}
else
#endif
#if GDK_WINDOWING_WAYLAND
if (GDK_IS_WAYLAND_WINDOW (window))
{
/* do wayland stuff */
}
else
#endif
{
/* do stuff for unsupported system */
}
This requires different GdkWindow types and we currently don't have
that, as only the GdkWindowImpl differs. With this method, every backend
defines a custom type that's just a simple subclass of GdkWindow. This
way GdkWindow behaves like all the other types (visuals, screens,
displays) and we can write code like the above.
This commit hides the GdkDisplayManager instance and class structs,
adds vfuncs for listing displays, opening displays, and getting and
setting the default display. The X11 backend has a derived
GdkDisplayManagerX11.
The gdk_display_manager_get() function is responsible for deciding on
which of the compiled in backends to use. Currently, it consults the
GDK_BACKEND environment variable and falls back to x11.
This commit hides GdkDragContext and GdkDragContextClass, adds
vfuncs for most drag context functionality, and turns the X11 DND
implementation into GdkDragContextX11. We also add vfuncs to
GdkDisplay for gdk_drag_get_protocol and to GdkWindow for
gdk_drag_begin, and implemenet them for X11.
Other backends need similar treatment and are broken now.
Add a GdkDisplay::get_app_launch_context vfunc, and a
gdk_display_get_app_launch_context that for X11 returns a subclass.
For win32 and quartz, the implementations were trivial, so we
just return a new GdkAppLaunchContext without subclassing. Since
the type of the context now depends on the display,
gdk_app_launch_context_set_display is deprecated.
The old functions to get core pointer and devices list are gone as
well. This slice is entirely replaced internally by multidevice
handling and may just go.
This function may be used to know the hardware device that triggered
an event, it could resort to the master device in the few cases there's
not a direct hardware device to relate to the event (i.e.: crossing events
due to grabs)
* _gdk_device_set_associated_device() did not allow NULL device
* GdkDisplay should dispose device manager to avoid devices
trying to touch the display in finalize
* GdkDeviceManagerXI did not ref devices in id hash
* GdkDisplayX11 did not ref devices in ->input_devices
