The 'selection-changed' signal is emitted unconditionally, even in the case
when there is no selection to be cleared. As a result, the subscriber receives
the initial signal and if he calls gtk_file_chooser_get_uri(), no value is
currently selected.
This might happen for slow filesystems where a fast-content-type might
be provided instead. Don't try to manipulate that content_type if it's
NULL, otherwise we'll either throw warnings (at best) or crash (at
worse).
.osd suggests a particular color/background/hover style, while .circular
only suggests roundness. So for buttons that use both classes, make sure
the former takes precedence with regard to background/hover.
We want expander arrows to be vertically centered in their row, so we
pass the cell area's height to the renderer.
However, if the cell area's height is an odd number while the
"expander-size" style property is an even number, or vice versa, the
arrow will be centered in a half pixel, and fuzzily rendered.
So, round the render height to the same parity as the expander-size.
(This is not necessary for the arrow width because it's assumed equal
to the "expander-size" style-property.)
An expander arrows's render width is supposed to be derived from the
"expander-size" style property.
However, we are actually rendering it for a width equal to
expander-size + 1. This results in ugly blurry rendering.
There is a comment justifying this "+ 1", which has been there for
almost 2 decades. But the justification doesn't seem to apply to
the current code, so the original motivation is likely obsolete.
Let's remove this "+ 1" to render the arrow to a width exactly equal
to the "expander-size" style property.
This reverts commit d6a29e1b8c.
It fixed blurry rendering of expander arrows.
However, it also introduced a regression in that the arrows are no
longer vertically centered if rows are taller than twice the
expander-size style property.

Call gtk_widget_set_allocation after chaining up to parent class
to ensure that GtkInfoBar has correct allocation. Otherwise x and y
is set to zero causing wrong window position in gtk_info_bar_realize.
This fixes info-bar-message-types.ui reftest.

Epiphany is doing something weird after calling gtk_window_close(),
because by the time the callback executes, the window has no GdkWindow.
Frankly, I don't know what's happening there, but we should probably not
crash.
Fixes#2424
link target uses `$selected_bg_color` and `$selected_fg_color` for the
definition of some selectors (e.g. selected).
While `$link_color` and `$link_visited_color` are based on
`$selected_bg_color`, this does not seem coherent.
Replacing `$selected_*g_color` in link target style with link colors
defined in `_colors.scss file`.
GTK caches the settings per display in a static `GArray`, keeping a
reference to the `GdkDisplay` as the key.
However, when closing the display, the corresponding entry is not
removed from the cache in `GtkSettings`.
So when reopening again a `GdkDisplay`, if the new address matches one
of the previously closed display, the cache will return the existing
`GtkSettings` from the cache, which still holds a reference to the old
`GdkScreen` which was freed along the `GdkDisplay`.
To avoid the issue, make sure to remove the `GdkDisplay` and
corresponding `GdkSettings` when closing the `GdkDisplay`.
Also, care must be taken not to recreate the `GdkSettings` and re-add
the `GdkDisplay` to the cache once the display is closed, and make sure
callers of `gtk_settings_get_for_display()` can deal with a returned
value being `NULL` if the display is closed.
Fixes: commit 360a3c1690 - "Use a cheaper way to store settings per
display"
- many moons and some iterations later, these are the suggested
general typographic styles. Already being referenced in apps like
Banner Viewer (for now shipping custom definitions)

Touchpad gestures have only a single event sequence. The current
'center' of the gesture is the starting point + accumulated deltas.
Update gtk_gesture_get_bounding_box_center() accordingly.
When we have a default action set on the infobar, activate it
for clicks anywhere in the infobar. Also add an .action style
class in this case, so we can add a hover highlight to the infobar
just for this case.
When a remote instance of a GTK application implementing the Startup
Notification protocol gets spawned it will pass the startup sequence
ID as "platform data" to the main instance. Thus, we need to make sure
that the startup sequence gets completed in that case, since the remote
instance won't do it by itself, since it won't map any top level window.
Checking for this "platform data" in the implementation of the after_emit()
virtual method in the primary instance should be a good place to do so, since
the existence of such data proves that a remote instance has been spawned.

Always insist on at least 1px, even if the thumbnail we're turning into
an icon was 256 * 3 and should be scaled to 32 * 3/8.

It's currently used only to not include the insert emoji option in the
context menu, but it's still possible to show the emoji chooser in both
GtkEntry and GtkTextView using the key bindings.
