Add a new ::measure vfunc similar to GtkCssGadget's that widget
implementations have to override instead of the old get_preferred_width,
get_preferred_height, get_preferred_width_for_height,
get_preferred_height_for_width and
get_preferred_height_and_baseline_for_width.
These days exposure happens only on the native windows (generally the
toplevel window) and is propagated down recursively. The expose event
is only useful for backwards compat, and in fact, for double buffered
widgets we totally ignore the event (and non-double buffering breaks
on wayland).
So, by not setting the mask we avoid emitting these events and then
later ignoring them.
We still keep it on eventbox, fixed and layout as these are used
in weird ways that want backwards compat.
GtkCalendar can have an invalid date — mostly at initialization. This
means that GDateTime construction may fail. We need to handle that case
gracefully, like the old code did.
This fixes the `notify` test suite, which started failing with:
/Notification/GtkCalendar:
GLib-CRITICAL **: g_date_time_get_day_of_week: assertion 'datetime != NULL' failed
inside the Continuous builder.
If the first of the month was falling on a Sunday, we would not
render any days of the previous month, and instead show two weeks
of the next month at the bottom. Improve this by showing one week
of each.

When allocated more than the requested height, GtkCalendar
was 'falling apart'. Not only was the main part rendered
at the far end of the allocation, clicking on days was
broken in this scenario.
Fix this by always placing the main part directly under
the header and day names.

It may be unusual, but handlers of day-selected may want to transfer
focus somewhere else, without getting it reset back right after by/to
the calendar. This makes popovers demo work on the calendar again, for
one...
When trying to drag, we currently the position of the first motion
event to determine where the drag came from. This might be alright
in the case of the old animation, but the data will be inaccurate
if the user has moved the pointer quite a bit since pressing the
cursor to start dragging. While we could monkey patch the GdkEvent
at the widget layer, this is unintuitive and strange.
Add a new API that takes a set of pointer coordinates describing
the origin of the drag. Additionally, adapt most widgets to use
it and use it with correct coordinates.

This replaces the previously hardcoded calls to gdk_window_set_user_data,
and also lets us track which windows are a part of a widget. Old code
should continue working as is, but new features that require the
windows may not work perfectly.
We need this for the transparent widget support to work, as we need
to specially mark the windows of child widgets.

This allows drawing calendar arrows in all possible states the main widget may
be in.
The arrow_state array is converted into a bit field since it only really needs
to store boolean information about prelight for each arrow.
This commit introduces a new setting, gtk-visible-focus, backed
by the Gtk/VisibleFocus X setting. Its three values control how
focus rectangles are displayed.
'always' is equivalent to the traditional GTK+ behaviour of always
rendering focus rectangles.
'never' does what it says, and is intended for keyboardless
situations, e.g. tablets.
'automatic' hides focus rectangles initially, until the user
interacts with the keyboard, at which point focus rectangles
become visible.
