Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
This is a bit of filechooser internals that gets shared with
nautilus, which is fine, but it shouldn't be part of our
public API. There are no other users than nautilus.
I hadn't noticed the :drop() pseudo state in the CSS4 Selectors
spec when I added this a while ago. This commit renames
GTK_STATE_FLAG_DND to GTK_STATE_FLAG_DROP_ACTIVE and adds
:drop(active) as equivalent to the :dnd pseudo state.
Under X11, popovers are always constrained to the toplevel
window. Under Wayland, they aren't. This commit adds a
property that allows to explicitly constrain popovers to
the toplevel, giving them the same behavior under Wayland
as under X11.

This commit makes button always draw background and frame.
Buttons with relief none get a new style class, FLAT, which
allows themes to style these buttons as they like.
We also (finally) mark GTK_RELIEF_HALF as deprecated. It
has never done anything different from GTK_RELIEF_NORMAL.

This phase is meant to run in the default widget handlers, as opposed
to externally as in the bubble/capture phase. This will be most usually
the expected phase for every controller replacing code in event handlers
in GTK+, just so invocation and triggering order is kept unaltered.
Gestures attached with this phase will expect callers to have it
receive events through gtk_event_controller_handle_event(), but
the gesture will still be notified of sequence state changes,
grabs, etc...
A controller can be optionally hooked on the capture or the bubble
phase, so the controller will automatically receive and handle events
as they arrive without further interaction.
Try to do a better job of keeping example content
from being too wide. It is often rendered as <pre>
text so the only time we can wrap it is in the source.
It is best to full break lines at all punctuation and
to try to keep the width under 70 chars or so.
