On wayland, such axes are per-tool, we must update device capabilities
on the fly as new tools enter proximity, first the slave device so
it matches the current tool, and then the master device so it looks
the same than the current slave device.
Only the management of tablets and tools is added so far. No tablet events
are yet interpreted.
As it's been the tradition in GTK+, erasers are split into their own device,
whereas the rest of the tools are meant to be routed through the
GDK_SOURCE_PEN device. Both pen/eraser devices are slaves to a master
pointer device, separate to wl_pointer's. This is so each tablet can
maintain its own cursor/positioning accounting.

This will enable multiple "pointers" to have separate data here.
Will come out useful when adding support for tablets, as they
will have a separate cursor for all purposes.
We have no proximity events in XI2, but the changes around this property
will roughly match the times when it would be emitted, so can be used
as the base to emulate these.
Changes for this property will be received independently of the pointer
position, so we should take care to not emit it if the pointer is not
above any known window, emission around crossing events should be
taken care of too, left for a next commit.
On wayland we get separate master/slaves for each tablet, we will
need to receive crossing events for each master pointer if there's
more than one around.
Axis labels are very X specific, and are not really possible to port to other
backends such as Wayland. As such, it makes more sense to use GdkAxisUse and
GdkAxisUseFlag in order to determine the axis capabilities of a device and draw
their axes.

Because there are multiple different types of styluses that can be used with
tablets, we have to have some sort of identifier for them attached to the
GdkDeviceTool, especially since knowing the actual tool type for a GdkDeviceTool
is necessary for matching up a GdkDeviceTool with it's appropriate
GdkInputSource in Wayland (eg. matching up a GdkDeviceTool eraser with the
GDK_SOURCE_ERASER GdkInputSource of a wayland tablet).

On the devices and backends that support it, this signal will be emitted
on slave/floating devices whenever the tool they are interacting with
changes. These notifications may also work as a sort of proximity events,
as the tool will be unset when the pen moves too far.
For backends, gdk_device_update_tool() has been included, all that should
be done on their side is just calling this whenever any tool might have
changed.
GdkDeviceTool is an opaque object that can be used to identify a given
tool (eg. pens on tablets) during the app/device lifetime. Tools are only
set on non-master devices, and are owned by these.
The accounting functions are made private, the only public call on
GdkDeviceTool so far is gdk_device_tool_get_serial(), useful to identify
the tool across runs.
We use a label_sizing_box to make sure the headerbar can always contain
both a title and a subtitle without resizing when showing/hiding either
of them, but we should only do that for the height; the min width of the
label_box can be larger than that of the label_sizing_box.
Commit cdc580463e made it so that
unresizable windows can't be smaller than a set default size but it
lost the logic to ensure these windows remain at least big enough to
comply with their requisition.

When we invalidate a window we need to also invalidate all child windows
that are native (non-native are automatically invalidated as we track
invalidation once per native window only). This was done in a pretty
inefficient way, recursing over the entire tree.
This makes the invalidation much faster by only looking at the native
children of the native window we're in, filtering out those that
are not a descendant of the client side window we're interested in.
Given that there are very few native subwindows this is much faster.
We were missing all of the status directories, and a few sizes.
This was causing us to not find image-missing on systems without
hicolor icon theme (this basically only happens on Windows).
