The colors demo was leaking a reference to its model.
This was showing up as crash when you manage to close
both the demo window and the main window while the
sorting is ongoing.
Drop the homegrown highlighting code, and just use highlight
to produce Pango markup.
When using an external highlighter, we can also highlight css,
xml, headers, at least.
We can't use the ::destroy signal anymore; use
a weak ref instead, and make ensure the entry
stays around long enough for us to finish the
cleanup.
Fixes: #3004
No need for an intermediate box widget here;
we can just use a box layout. As a side-effect,
this fixes the theme to apply to the selection.
Fixes: #3005
ss00 doesn't exist, and we use xxxx as placeholder
for 'default' choices in alternatives. Add a warning
in case we run across invalid OpenType feature tags
in fonts.
Fixes: #2962
Some implementations of the ES 1.00 shader (such as Google's ANGLE) do
not like the 'f' suffix for floats, so just drop it, as it should be
harmless to drop.
Make both gtk_grid_view_new and gtk_grid_view_new_with_factory
take a model as first argument, and make all arguments
allow-none and transfer full.
Update all callers.
Make both gtk_list_view_new and gtk_list_view_new_with_factory
take a model as first argument, and make all arguments
allow-none and transfer full.
Update all callers.
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.
This is for consistency with other wrapping list constructors.
We want them all to be transfer full, allow-none.
Also make the constructor return GtkMultiSelection *.
Update all callers.
Make gtk_tree_list_model_new() take the root model
as first argument, and make it transfer full, for
consistency with other wrapping list constructors.
Update all callers.
Still missing here: Make the model property writable,
and allow passing NULL in the constructor.
To build a better world sometimes means having to tear the old one down.

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

That way, demo windows can be maximized and multiple demos can run at
once.
It's especially useful when using --run because the main window is
invisible then.
When the search entry disappears on Escape,
reset the search string to "", so we don't
end up with a filtered list and no obvious
way to remove the filtering.
