Replace generic setter code

Instead of going through a big switch of all properties,
make the new_compute() functions for each values struct
directly set its members. This way, we can also avoid the
border-width special case for more properties.

-## 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.
-
