ca9b06878d switch: Hide internal structure from a11y
According to section 7.1 of WAI-ARIA, the switch role
has the "Children presentational" characteristic, which
indicates that children should not be represented in
the a11y tree.

2ef4be21c8 switch: Initialize accessible state
The checked state defaults to undefined, so we need
to set it to the desired false state.

property is toggled.

c63087a563 Remove ATK
To build a better world sometimes means having to tear the old one down.
        -- Alexander Pierce, "Captain America: The Winter Soldier"

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

b81bbde7c8 gtkswitch: Don't be eager in accepting the gesture
The gesture should be accepted whenever it triggers uncancellable
actions in the widget. This means it should be accepted if the
click does result in toggling the switch.

This leaves the pan gesture room to handle dragging the handle.

2d5cf2b4c4 Drop fallback-c89.c
We require a C compiler supporting C99 now. The main purpose of
these fallbacks was for MSVC. From what I can see this is now all supported
by MSVC 2015+ anyway.

The only other change this includes is to replace isnanf() with the
(type infering) C99 isnan() macro, because MSVC doesn't provide isnanf().

b93631164f Remove lots of focus vfuncs

edc31a264c widget: Add a :focusable property
Add back a property that determines whether an individual
widget will accept focus or not. :can-focus prevents the
focus from ever entering the entire widget hierarchy
below a widget, and :focusable just determines if grabbing
the focus to the widget itself will succeed.

See #2686

632524f679 Reinstate expected focus behavior
After the :can-focus change in the previous commit, widgets
need to set suitable focus and grab_focus implementations
to implement the desired focus behavior.

This commit does that for all widgets.

828c36636c va_marshaller: add various va_marshallers
We don't need to cover every case with a va_marshaller, but there are a
number of them that are useful because they will often only be connected
to by a single signal handler.

Generally speaking, if I opened into a file to add a va_marshaller, I just
set all of them.

58d9c3d5bd switch: Update state labels when needed

5c50e48156 Add fallback glyphs for GtkSwitch states
Even though the IEC power glyphs are part of Unicode 9.0 (released in
2016) not all fonts have them.

To avoid showing the hexbox of doom when the system font does not have
the glyphs we'd like to use, add a fallback pair, using the old glyphs
we suggested when the labels were translatable.

ba9b0c6f7d Use the IEC power symbols for GtkSwitch labels
Unicode 9.0 introduced glyps for the "on" and "off" power states, in the
form of:

 - U+23FD POWER ON SYMBOL, or ⏽
 - U+2B58 HEAVY CIRCLE, or ⭘

With `HEAVY CIRCLE` as "power off symbol" selected to avoid adding yet
another circle to the standard.

Since we moved GtkSwitch to always show glyphs instead of (translatable)
strings, asking the localisation teams to either come up with a suitable
short string to replace the English "ON" and "OFF", or to fall back to
Unicode glyphs, we should ensure we're using the appropriate symbols to
begin with.

See also: gtk!503 for the corresponding gtk-3-24 change.
