* Move GTK compatibility macros into a separate header
* Fix Cairo compatibility checks
* Move Glib-namespaced definitions to GtkCompat header
* Remove unused stringify definitions since we're using fmtlib
* Automatically (re)order include directives (GTK client)
Include our headers first to ease IWYU enforcement.
* Fix includes missing from headers (GTK client)
* Fix build on Mac after includes reordering
* Use `Gio::List{Model,Store}` for torrents
Switch from `Gtk::{TreeModel,ListStore}` in preparation for cell
renderers deprecation in GTK 4.10. That will require switching to the
new view classes (`Gtk::{Column,List}View`) which only work with `Gio`
models. Implement an adapter to support GTK+ 3 where the old view class
(`Gtk::TreeView`) only works with `Gtk` models; it is effective enough
but requires a signal connection per item to notify on row changes.
Refactor filtering and sorting (which now happen over the new model) to
use compatible `Gtk::Filter` and `Gtk::Sorter` classes. Although these
classes are only present in GTK 4, the abstraction is suitable for GTK+
3 as well so make our subclasses work for both versions.
Since items (of `Torrent` class) of the new model provide only a very
limited (by design) layer of compatibility with GTK+ 3 way of doing
things, refactor selection handling to do it the new way. Move selection
helpers into `MainWindow` to abstract them away since new view classes
handle it differently.
* Improve session load performance based on profiling results
* Make compact mode switch work for both GTK 3 and 4
* Implement GTK 4-specific view gesture handling
* Fix torrents view context menu on GTK 4
* Explicitly show/hide menubar on startup/teardown
* Switch from `Gtk::Pixbuf` to `Gio::Icon` for views
* Support GTK 4 exceptions based on `std::exception`
* Fix options menu setup with GTK 4
* Use `delete-event` (GTK 3) and `close-request` (GTK 4) signals to handle window clousure
* Add custom file chooser button implementation
GTK 4 drops FileChooserButton widget and suggests implementing it using
Button.
* Add helpers to set X11 hints with GTK 4
* Remove `HigWorkarea` class that's no longer used
* Make main menu shortcuts work with GTK 4
* Make drops work in main window and make dialog with GTK 4
* Remove unused `gtr_action_get_widget()` helper
* Fix text direction mark setup with GTK 4 (due to switch to enum class)
* Fix file tree font size calculation with GTK 4
* Fix crash during shutdown with GTK 4
* Switch from `RadioButton` to `CheckButton` for compatibility with GTK 4
* Fix opening files with GTK 4
* Rework torrent cell renderer to support both GTK 3 and 4
* Disable system tray icon support with GTK 4
* Fix windows positioning with GTK 4
* Fix focus event handling with GTK 4
* Adapt to tree model row/iterator changes in GTK 4
* Adapt to toplevel/root window changes in GTK 4
* Adapt to clipboard changes in GTK 4
* Adapt to icon/theme changes in GTK 4
* Adapt to file/path changes in GTK 4
* Random leftover fixes for GTK 4 compatibility
* Clean up unused code
* Move GTK 3 *.ui files into a subdirectory
* Add GTK 4 *.ui files
* Search for both GTK 3 and 4 during configuration
* (C++) Macros should not be used to define constants
* (C++) Memory should not be managed manually
* (C++) "void*" should not be used in typedefs, member variables, function parameters or return type
* (C++) When the "Rule-of-Zero" is not applicable, the "Rule-of-Five" should be followed
* (C++) "switch" statements should have "default" clauses
* (C++) "explicit" should be used on single-parameter constructors and conversiosn operators
* (C++) Non-const global variables should not be used
