gtknotebookpageaccessible: do not fallback to child accessible for extents

See merge request !2924

When the notebook page does not have a label, it should not fallback to
asking its child accessible for extent, since the child might be asking
exactly the converse when it is a socket, thus getting in an infinite
loop. When the page does not have a label, is does not really make sense to
give it an extent anyway.

Adwaita: Stop using $button_fill (for gtk-3-24)

See merge request !2829

The $button_fill hack for button.circular is pretty awkward and is
currently broken. Instead of relying on it, allow the button() mixin to
have an additional background-image optionally.

Accumulate existing velocity when decelerating from a swipe if the swipe
velocity is above a certain fraction of that existing velocity.

Highlight treeview header button border with more contrasting color on hover

See merge request !2467

The existing treeview header button border in GTK3 is close to
invisible. The preferred way to find the border for a treeview column
is to hover the mouse near the beginning of the header button text
expecting the default cursor to switch to 'col-resize' cursor. This
works only when all column headers in the view are left aligned. After
adding a few numeric columns to the view, whose headers are right
aligned, it becomes really hard to find the location of the border
between a left aligned and right aligned column header.

This change addresses the issue by using high contrast colors for
borders of treeview header button - in line with the colors used in
Adwaita theme in GTK4.

wayland: Bail loudly if invalid geometry is set

See merge request !2808

There is some bug somewhere where the geometry ends up being correct.
Mutter didn't handle this gracefully, and is to be changed to simply
respect the protocol and error out the client that sends bogus data.

Prepare for this by instead of sending bogus data, complain loudly if it
would happen dropping the invalid geometry on the floor instead of
sending it.

Set modifier state of scroll events, so Ctrl-scroll

Fixes: #2733

pango_font_family_get_face() was only introduced
in pango 1.46. Work around this for older releases.

When the level does not include the style, we only
include one face of each family in the list. But we
were just choosing the first face (typically, a light
or extra-light style). Improve this by picking the
default face (normally, the regular face), which is
the expected behavior.

gdk: Fix parent relative background crash

See merge request !2753

When setting a window's background to ParentRelative on X11, the window
depths must match to avoid a BadMatch error. Query the X server for the
parent window rather that relying on the parent passed to
gtk_window_new() to prevent crashes with reparented windows.

gestureswipe: Count last event when calculating velocity

See merge request !2714

The last event, matching lifting the finger/releasing the mouse button,
is important when there's a large delay between it and the previous events,
as in when performing a movement, stopping, then releasing fingers as
opposed to doing a swipe.

If this event is skipped, doing this will result in kinetic deceleration
matching the previous finger movement, while the expected behavior would
be no deceleration.

gtkapplication-dbus: Initialise screensaver-active property

See merge request !2716

Bob Ham authored Sep 06, 2019 and Alexander Mikhaylenko committed Oct 19, 2020

When GtkApplication starts listening to the screensaver's D-Bus
status, the screensaver-active property is not initialised and
applications making use of the property are out of sync until the
first state change.  Any application starting when the screensaver is
active will think it's inactive.

To fix this, we set the property when we first start monitoring the
screensaver.
