Prevent subclassing of gestures For now, at least. We do this by hiding the instance and class structures in private headers.

eventcontroller: Add vfuncs to (un)set widget This is the first step towards refactoring how widgets deal with event controllers. In the future, the widget will treat controllers the same way it treats child widgets: 1. The controllers will be created without a widget. 2. There will be gtk_widget_add/remove_controller() functions to add or remove controllers. 3. The widget will hold a reference to all its controllers. This way we will ultimately be able to automate controllers with ui files.

Pass translated coordinates outside the event We want to make events readonly, so stop translating their coordinates and instead pass the translated coordinates separately, when propagating events.

void (* reset) (GtkEventController *controller);
New focus change handling Instead of relying on gdk's antiquated crossing events, create a new GtkCrossingData struct that contains the actual widgets, and a new event controller vfunc that expects this struct. This also saves us from making sense of X's crossing modes and details, and makes for a generally simpler api. The ::focus-in and ::focus-out signals of GtkEventControllerKey have been replaced by a single ::focus-change signal that takes GtkCrossingData as an argument. All callers have been updated.

eventcontroller: Add private ::filter method This will be used right before handle_event() in order to filter out events, useful to make the previous "no touchpad events" behavior the default, and have gesture subclasses include manually the touchpad events they handle.

GtkEventController: Add some comment describing the filter_event private vfunc It might not be entirely clear what the boolean return value means. https://bugzilla.gnome.org/show_bug.cgi?id=770026
