A GskGLShader is an abstraction of a GLSL fragment shader that
can produce pixel values given inputs:
* N (currently max 4) textures
* Current arguments for the shader uniform
Uniform types are: float,(u)int,bool,vec234)
There is also a builder for the uniform arguments which are
passed around as immutable GBytes in the built form.
A GskGLShaderNode is a render node that renders a GskGLShader inside a
specified rectangular bounds. It renders its child nodes as textures
and passes those as texture arguments to the shader. You also pass it
a uniform arguments object.
This way the child widgets can rely on the renderer (for example what
type it is) to decide details about how they render (such as if they
should use OpenGL shaders).
This property was only used until now when
there was neither an icon nor a label set,
for arrow direction and popover placement.
Starting with Gtk4, a GtkMenuButton with a
label shows an arrow at the right (in LTR)
of the label. Allow disabling the arrow or
changing its direction using the direction
property, to have a way to restore a Gtk3-
like look or to improve popover placement.
Fixes#2811.
Kinetic scrolling (and begin/end tracking) broke with commit cab1dcb696
since the pointing device used on X11 does not get as much GdkInputSource
granularity as the source device used to have in GTK3.
Actually this is kinda pointless, devices incapable of smooth scroll
should send discrete events, without those devices in the picture, we
want kinetic scroll to apply on every other device capable of smooth
scroll, so just do that.

The texture that produce is upside-down, compared to what
GSK expects, so flip things around with a transform.
This fixes the shadertoy demo being upside-down after a
recent fix to avoid downloading and reuploading the texture.
... or gradients or borders or shadows. Instead, ensure that affines
have non-negative scale factors. Otherwise add a transform node.
The only place where this check is not necessary is color nodes, but
special casing them seems not worth it.
"inout" for the parameter ITER passed. This means that bindings would misjudge what
the function does. In the case of guile-gi, it would be misjudged for a predicate,
see gulie-gi bug 87.
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.

With the exception of gtk_buildable_get_id(), those are only used
to construct objects from XML descriptions, which is functionality
internal to GTK.
The API is therefore unlikely to be missed, and keeping it internal
means they can no longer unintentionally shadow object methods in
bindings with less namespacing; for example it's currently ambiguous
whether `infoBar.add_child()` refers to gtk_info_bar_add_child() or
gtk_buildable_add_child().
https://gitlab.gnome.org/GNOME/gtk/-/issues/3191
GtkBuildable's get_name()/set_name() methods may shadow
GtkWidget's methods. Avoid that by renaming the API to
get_buildable_id()/set_buildable_id(), which also reflects
the name of the XML attribute the API refers to.

Drop gtk_column_view_column_new_with_factory and
just make gtk_column_view_column_new accept a
nullable factory. This follows what we've been
doing elsewhere.
Update all callers.
The priv->in_button state that used to be relied upon for pointer
events has been reduced over time to a broken state, since the button
does not track crossing events anymore.
Make the coordinate-based checks apply for pointer events too, besides
touch events. This fixes GtkButton mistakenly emitting ::clicked with
pointer button releases outside the widget.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3121
Claiming early makes the contents unable to react to the touch press
event. Do this on GtkGestureDrag::update past a threshold, so the
child widget(s) can claim before the scrolledwindow does.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3125
This API is kinda stuck in the GdkEvent days, we now negotiate ownership
of the input sequence via GtkGestures. Remove it as it reflects a way to
work that was not exactly accurate and it will turn plainly wrong soon.
Just always tell the title and cell widgets to
clip their children to the right size. Otherwise
we risk things getting out of sync and unintended
overdraw.
Fixes: #3179
If we just parse a color, like image(#FFF), avoid allocating the
GPtrArray to store images. This happens in Adwaita for background images
of backdrop buttons. We save around 70 GPtrArrays this way.
The centered layout of the font previews don't look appealing
and make it harder to judge the relative width and weight of
the individual styles.
Fixes: #3188
In gtk_tree_view_build_tree with recurse=TRUE, the TEST_EXPAND_ROW
signal might invalidate the child iterator. Getting the iterator after
the signal (instead of before) fixes the issue.

- Move padding from parent row to child cell.
- Align horizontal sizing of cell with header button.
- Properly support GtkColumnView:show-column-separators.
- Change cell height with and without .data-table.
