It's not a portable API, so remove it. The corresponding backend
specific functions are still available, if they were implemented, e.g.
gdk_macos_monitor_get_workarea() and gdk_x11_monitor_get_workarea().
pandoc insists on using the xlink namespace for hrefs,
and the namespace setup doesn't carry over xi:includes.
My first fix was to tell pandoc to generate standalone
docbook documents, which makes it insert the xlink
namespace. But it also makes it wrap all sections and
chapters in articles, and that messes up our toc structure.
So, patch things up differently by stripping the xlink:
from hrefs via regex.
Yay for XML!
Make GdkEvents hold a single GdkDevice. This device is closer to
the logical device conceptually, although it must be sufficient for
device checks (i.e. GdkInputSource), which makes it similar to the
physical devices.
Make the logical devices have a more accurate GdkInputSource where
needed, and conflate the event devices altogether.
Besides the implicit x/y assumptions, devices don't have axes. Those
are actually provided by the GdkDeviceTool driving the device, and
different tools may have different axes.
It does not make sense to offer this API that can change beneath
someone's feet, we now have gdk_device_tool_get_axes() which is static
to the tool.
Use the label accessible role for GtkLabel. ARIA has some
ominous wording about it going way, but while we have it,
GtkLabel is the obvious candidate for carrying it.
Update the documentation and add a test.
In some cases we explicitly want to unset an accessible attribute; for
instance, an accessible property is gated on a widget property, and if
the widget property gets unset, the accessible property should be reset.
A dropdown without a model is useless, so accept a model
and expression in the constructor. Allow them to be NULL,
but consume them if given. This makes chained constructors
convenient without breaking language bindings.
Drop gtk_drop_down_set_from_strings() and instead add
gtk_drop_down_new_from_strings().
Update all users.

ATK served us well for nearly 20 years, but the world has changed, and
GTK has changed with it. Now ATK is mostly a hindrance towards improving
the accessibility stack:
- it maps to a very specific implementation, AT-SPI, which is Linux and
Unix specific
- it requires implementing the same functionality in three different
layers of the stack: AT-SPI, ATK, and GTK
- only GTK uses it; every other Linux and Unix toolkit and application
talks to AT-SPI directly, including assistive technologies
Sadly, we cannot incrementally port GTK to a new accessibility stack;
since ATK insulates us entirely from the underlying implementation, we
cannot replace it piecemeal. Instead, we're going to remove everything
and then incrementally build on a clean slate:
- add an "accessible" interface, implemented by GTK objects directly,
which describe the accessible role and state changes for every UI
element
- add an "assistive technology context" to proxy a native accessibility
API, and assign it to every widget
- implement the AT context depending on the platform

This flag causes pandoc to emit a proper doctype
declaration and, crucially, namespace declarations
for the xlink namespace that it insists on using
for href attributes. Without this, putting external
links in md documents doesn't survive the journey
through xml.
Add a table mapping event signals to their event controller
replacements, and a table mapping former GtkContainer
subclasses to their gtk_container_add replacement.
