Now all events structs are private, it doesn't make as much sense
having GdkEventPrivate wrapping allocating events. This is a first
step towards removing it.
It won't stand true anymore that the GdkEventType argument is the
first field of the GdkEvent* structs. All callers have been updated
to use event->any.type instead.
Instead of just passing the GdkContentFormats, we are now passing the
GdkContentProvider to gdk_drag_begin().
This means that GDK itself can now query the data from the provider
directly instead of having to send selection events.
Use this to provide the private API gdk_drag_context_write() that allows
backends to pass an output stream that this data will be written to.
Implement this as the mechanism for providing drag data on Wayland.
And to make this all work, implement a content provider named
GtkDragContent that is implemented by reverting to the old DND
drag-data-get machinery inside GTK, so for widgets everything works just
like before.
Scrolling a path bar is of marginal usefulness - you need to
find a really deep place in your filesystem hierarchy in order
to scroll one or two places at best. And the code we had for
this was not working. And it was using legacy event handlers.
Instead of fixing it, remove it.
This code was doing horrible things, and the atk documentation
for the focus tracking feature says that this is deprecated and
not used anymore. So lets not do it.
Mark the following signals as deprecated:
event, event-after, button-press-event, button-release-event,
touch-event, scroll-event, motion-notify-event, enter-notify-event,
leave-notify-event, property-notify-event, selection-clear-event,
selection-request-event, selection-notify-event, selection-received,
selection-get, proximity-in-event, proximity-out-event. Most
of these have suitable replacements in event controllers and
gestures already. The selection-related signals will soon be
irrelevant when selection handling moves to GDK.
Set G_ENABLE_DIAGNOSTIC=1 to see deprecation
warnings for uses of these signals.
Instead, pass the actions as part of gdk_drag_begin() and insist DND is
always managed.
A new side effect is that gdk_drag_begin() can now return %NULL.
We were allocating the progress bar to the full size
of the entry. This made entry icons loose their cursors,
since they were 'covered' by the progress bar, even though
it doesn't draw anything there.
We need to notify ATK the description changed when the tooltip text associated
with the widget changes and gtk_widget_accessible_get_description() would use
it as the description.

This is the replacement for selection usage.
Backend implementations for X11 (missing support for backwards compat
formats like COMPOUND_TEXT) and Wayland are included.
GTK code should be adapted to use gdk_drop_read_*() functions instead
of gtk_drag_get_data().
The fix is twofold. First, when checking that a corner is resizable, we must
check the constraints on both edges. Second, when checking either edge we
must include both perpendicular sides in order to allow those to be
resizable when the constraint does not allow resizing the edge being
checked.
