a546ae32d7 Remove all nicks and blurbs from param specs
Those property features don't seem to be in use anywhere.
They are redundant since the docs cover the same information
and more. They also created unnecessary translation work.

Closes #4904

This should fix our handling of fonts with AVAR.

We were doing unnecessary work here, which could
get really slow with some fonts. Just compute
the reverse charmap once and reuse it.

b7b6c147f9 fontchoserwidget: Do our own face filtering
Pango may not do this for us, so don't rely on it.
We only show one face with a given name, and we
prefer a variable face over a non-variable one.

The check for variable faces requires new Pango
API that will be in Pango 1.52.

2dc56a6e9b fontchooserwidget: Revise handling of named instances
Allowing to tweak the axes of named instances does
not do any harm. If we don't, we have to worry that
we need at least one non-named-instance in the face
list, and make it more obvious how to pick it out.

e9d8bf96e0 fontchooser: Avoid setting variations needlessly
Setting variations to their default value causes
them to show up in the serialization of the font
description - a font description has no idea about
the default values, so can't filter them out.

Avoid that.

752270253f fontchooser: Fix builds without PangoFT2
Currently, only if PangoFT2 is present and used it is supported
to retrieve the languages that are supported by a particular font.

If we don't have PangoFT2, remove the language filtering and the
sample text selection.

69d5dc7c9a fontchooser: Determine sample text intelligently
Look at the languages supported by a font, and pick
a suitable sample text from the pango list of sample
texts. We can only implement this on platforms using
fontconfig, since it relies on pangofc apis.

This bumps the pango dependency to 1.47.1.

1375fb4464 Change button hierarchy
A radiobutton without indicator is really just a togglebutton with a
group.

A radiobutton with indicator is really just a checkbutton with a group.

Make checkbutton its own widget not inheriting from GtkButton.
GtkRadioButton could be removed but it stays for now.

Radiobutton && !draw-indicator => Togglebutton
Checkbutton && !draw-indicator => Togglebutton

Radiobutton && draw-indicator => CheckButton + group

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

5080730728 listmodels: Stop respecting item-type
Simplify all view model APIs and always return G_TYPE_OBJECT as the
item-type for every model.

It turns out nobody uses item-type anyway.

So instead of adding lots of APIs, forcing people to think about it and
trying to figure out how to handle filter or map models that modify item
types, just having an easy life is a better approach.

All the models need to be able to deal with any type of object going
through anyway.

58b65d1bf6 fontchooserwidget: Port to listmodels
The port is kind of evil, in that it stores either a PangoFontFamily or a
PangoFontFace in the list, depending on if the fontchooser is configured
to select fonts or faces.
It also does not cache the font description anymore, so more calls to
pango_font_describe() may happen.

If both of these issues turn out problematic, the fontchooser would need
to resurrect GtkDelayedFontDescription again and put objects of that
type through the model.

These changes depend on Pango 1.46's introduction of listmodels and
various new getters, so the dependency has been upgraded.

afbff574f5 filechooser: Remove default size machinery
The FileChooser ToolKit (fctk) had its own machinery to handle default
sizes which was completely busted and trying to marshal random numbers
through the widget hierarchy that maybe made sense in 2012 but don't do
now.

Get rid of it, just keep the dialog's GSetting - which funnily enough
used to be written by the dialog but written by the widget.
But that's fctk for you.

042537cf0d fontchooser: Fix objects-finalize test
The treeview is evil and keeps reference cycles in the
form of various tree row references. That gets cleaned up
if you explicitly gtk_widget_destroy the treeview. But since
07f2024bfc, the scrolled window no longer destroys
its child, exposing this issue as a reference leak in
the objects-finalize test.

The font chooser widget is affected here because it calls
gtk_tree_view_scroll_to_path from init(), which creates one
of those reference cycles. Work around this in the font
chooser by unsetting the tree view model in dispose, which
clears up this cycle.
