-## GTK CI infrastructure
-
-GTK uses different CI images depending on platform and jobs.
-
-The CI images are Docker containers, generated either using `docker` or
-`podman`, and pushed to the GitLab [container registry][registry].
-
-Each Docker image has a tag composed of two parts:
-
- - `${image}`: the base image for a given platform, like "fedora" or
-   "debian-stable"
- - `${number}`: an incremental version number, or `latest`
-
-See the [container registry][registry] for the available images for each
-branch, as well as their available versions.
-
-### Checklist for Updating a CI image
-
- - [ ] Update the `${image}.Dockerfile` file with the dependencies
- - [ ] Run `./run-docker.sh build --base ${image} --base-version ${number}`
- - [ ] Run `./run-docker.sh push --base ${image} --base-version ${number}`
-   once the Docker image is built; you may need to log in by using
-   `docker login` or `podman login`
- - [ ] Update the `image` keys in the `.gitlab-ci.yml` file with the new
-   image tag
- - [ ] Open a merge request with your changes and let it run
-
-### Checklist for Adding a new CI image
-
- - [ ] Write a new `${image}.Dockerfile` with the instructions to set up
-   a build environment
- - [ ] Add the `pip3 install meson` incantation
- - [ ] Run `./run-docker.sh build --base ${image} --base-version ${number}`
- - [ ] Run `./run-docker.sh push --base ${image} --base-version ${number}`
- - [ ] Add the new job to `.gitlab-ci.yml` referencing the image
- - [ ] Open a merge request with your changes and let it run

-Overview of Changes in GTK 3.98.0
-=================================
-
-  While this release gets significantly closer to what we aim for in GTK 4,
-  there are still a few big items outstanding that we are currently working
-  on:
-
-  - Event controllers for keyboard shortcuts
-  - Movable popovers
-  - Row-recycling list and grid views
-  - Revamped accessibility infrastructure
-  - Animation API
-
-  We will do further 3.98.x snapshots as these land.
-
-  *****************
-
-* The DND refactoring has been completed. The GTK API for DND has been turned
-  into event controllers: GtkDragSource and GtkDropTarget. Support for file
-  transfers via file transfer portal has been added for both DND and the clipboard.
-
-* Child surfaces have been removed. GDK only supports toplevel and popup surfaces
-  now. The client-side window implementation has been removed too. On the GTK side,
-  the GtkNative interface has been introduced for widgets that have their own
-  surface. This cleanup is not 100% complete yet.
-
-* Global positions and related apis such as gdk_surface_move are no longer available.
-  
-* A constraint-based layout manager has been added.
-
-* Many classes have been made explicitly non-subclassable, and the widget hierarchy
-  has been simplified, by making widgets derive directly from GtkWidget instead of
-  a container.
-
-* Menu-related changes:
- - GtkMenu, GtkMenuBar and related classes have been removed. They are being replaced
-   by GMenu and popover-based variants. Popover menus can now do traditional, nested
-   menus, and model buttons show accelerators.
- - Context menus are no longer created with ::populate-popup signals, but use menu
-   models and actions.
- - Widget actions can be created in class_init, with gtk_widget_class_install_action.
- - GtkToolbar has been removed as well.
-
-* Text-related changed:
- - Text cursor blinking has been made smooth.
- - GtkTextView is caching rendernodes for the visible text range now, improving the
-   scrolling performance of text.
- - Add a simple undo stack for text edits has been added.
-
-* The native Win32 filechooser backend supports choices.
-
-* GtkTreeView renders tree and grid lines with textures.
-
-* GtkEmojiChooser has been made public.
-
-* GtkGestureMultiPress has been renamed to GtkGestureClick.
-
-* GtkWidget has api to handle style classes: gtk_widget_add_style_class.
-  This is the first step towards moving away from GtkStyleContext.
-
-* X11-specific changes:
- - XI2 is now mandatory
- - The xim input method has been removed
-
-* Wayland-specific changes:
- - The loading of cursor themes has been improved to load cursors on demand,
-   and no longer relies on libwayland-cursor.
-
-* The GL renderer is now sharing icon and glyph caches for all surfaces,
-  and has better support for blurring and shadow rendering.
-
-* Performance-related changes:
- - GTK provides profiling information for Sysprof when launched with GTK_TRACE=1.
- - Css computation has been optimized
- - Css lookups are using a Bloom filter
- - Icon loading IO has been moved to a thread
-

+/* Change Display
+ *
+ * Demonstrates migrating a window between different displays.
+ * A display is a mouse and keyboard with some number of
+ * associated monitors. The neat thing about having multiple
+ * displays is that they can be on a completely separate
+ * computers, as long as there is a network connection to the
+ * computer where the application is running.
+ *
+ * Only some of the windowing systems where GTK runs have the
+ * concept of multiple displays. (The X Window System is the
+ * main example.) Other windowing systems can only handle one
+ * keyboard and mouse, and combine all monitors into
+ * a single display.
+ *
+ * This is a moderately complex example, and demonstrates:
+ *
+ *  - Tracking the currently open displays
+ *
+ *  - Changing the display for a window
+ *
+ *  - Letting the user choose a window by clicking on it
+ *
+ *  - Using GtkListStore and GtkTreeView
+ *
+ *  - Using GtkDialog

+/* Menus
+ *
+ * There are several widgets involved in displaying menus. The
+ * GtkMenuBar widget is a menu bar, which normally appears horizontally
+ * at the top of an application, but can also be layed out vertically.
+ * The GtkMenu widget is the actual menu that pops up. Both GtkMenuBar
+ * and GtkMenu are subclasses of GtkMenuShell; a GtkMenuShell contains
+ * menu items (GtkMenuItem). Each menu item contains text and/or images
+ * and can be selected by the user.
+ *
+ * There are several kinds of menu item, including plain GtkMenuItem,
+ * GtkCheckMenuItem which can be checked/unchecked, GtkRadioMenuItem
+ * which is a check menu item that's in a mutually exclusive group,
+ * GtkSeparatorMenuItem which is a separator bar, GtkTearoffMenuItem
+ * which allows a GtkMenu to be torn off, and GtkImageMenuItem which
+ * can place a GtkImage or other widget next to the menu text.
+ *
+ * A GtkMenuItem can have a submenu, which is simply a GtkMenu to pop
+ * up when the menu item is selected. Typically, all menu items in a menu bar
+ * have submenus.
