- Move the class to the Deprecated section.
- Warning at the bottom of the class description.
- A missing property was not marked as deprecated.
- Update doc of gtk_container_set_border_width() to not mention
GtkAlignment.

This fixes an issue where the theme-provided border-width prevents
dialog contents from lining up properly with the headerbar. To make
this work in message dialogs, we have to explicitly set the border-
width of the action area to 0.
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.
Resize modes don't work anymore, both because nobody ever uses them and
because the frame clock changed the way things work quite a bit. So we
don't want to advertise them as a good idea.

GtkAssistant is bending the rules about child properties
of non-direct children, and the recent fix to accomodate
GtkInfoBar changes broke things. The effect was that child
properties of assistant pages in ui files were just not
applied, so all pages ended up without titles and with
the normal page type, leading to broken assistants all
over the place.

Packing properties in ui files are parsed and handled by
the container, which assumes that the child is a direct
descendant. For internal children, this is inconvenient,
because we don't want to reconstruct the entire internal
structure between the container and the child in the ui
file.
It would be best to not specify packing properties
in that case, but since existing ui files do this for
GtkInfoBar and we are about to change the internal
structure of GtkInfoBar, be more forgiving here.
Use g_string_assign to avoid issues with assigning GString's internal
buffer back to the same string. This can happen when no translations are
available and _gtk_builder_parser_translate returns back the same
pointer that was passed in.
This fixes a regression from commit e9f182e37a
that caused GtkComboBoxText <items> from GtkBuilder to show up empty if
no translations are available.

Now that we're not drawing the GdkWindows by themeselves we need to
propagate into children in the same order as the windows were painted
otherwise apps can't rely on stacking order to overlay children.
This is still not 100% the same as the old behaviour, because we're
treating all windows that are part of a window at the same time (to allow
e.g. opacity groups), and we're only looking at order for the main
windows of a widget. However, this fixes at least the ordering
of the gnome-boxes fullscreen overlay toolbar.

We now consider non-native windows non-opaque, which means any invalid
area in a subwindow will also be invalid all the way up to the nearest
native windows. We take advantage of this by ignoring all expose events
on non-native windows (which typically means just the toplevel) and instead
propagating down the draw() calls to children directly via
gtk_container_propagate_draw.
This is nice as it means we always draw widgets the same way, and it
will let us do some interesting ways in the future.
We also clean up the GtkWidget opacity handling as we can now always
rely on the draing happening via cairo.
We can't really just draw by walking down the widget hierarchy, as
this doesn't get the clipping right (so e.g. widgets doing cairo_paint
may draw outside the expected gdkwindow subarea) nor does it let
us paint window backgrounds.
So, we now do multiple draws for each widget, once for each GdkWindow,
although we still do it on the same base cairo_t that we get for the
toplevel native window. The difference is only the clipping, the rendering
order, and which other widgets we propagate into.
We also collect all the windows of a widget so we can expose them inside
the same opacity group if needed.
NOTE: This change neuters gtk_widget_set_double_buffered for
widgets without native windows. Its impossible to disable
the double buffering in this model.

The fix here is slightly different. We make
_gtk_builder_parser_translate return a const char * instead of
a dup'ed string, and fix up the callers.
This modifies the size machinery in order to allow baseline support.
We add a new widget vfunc get_preferred_height_and_baseline_for_width
which queries the normal height_for_width (or non-for-width if width
is -1) and additionally returns optional (-1 means "no baseline")
baselines for the minimal and natural heights.
We also add a new gtk_widget_size_allocate_with_baseline() which
baseline-aware containers can use to allocate children with a specific
baseline, either one inherited from the parent, or one introduced due
to requested baseline alignment in the container
itself. size_allocate_with_baseline() works just like a normal size
allocation, except the baseline gets recorded so that the child can
access it via gtk_widget_get_allocated_baseline() when it aligns
itself.
There are also adjust_baseline_request/allocation similar to the
allocation adjustment, and we extend the size request cache to also
store the baselines.
We need to disconnect the frame clock when we unrealize (at which
point the old clock is still alive) not in destroy(). Since there
is no common unrealize for containers, trigger this from GtkWidget.
Instead of having gdk_frame_clock_request_frame() have
gdk_frame_clock_request_phase() where we can say what phase we need.
This allows us to know if we get a frame-request during layout whether
it's just a request for drawing from the layout, or whether another
layout phase is needed.

Instead of using 1 global queue for both resizes and style validation,
use 2 queues. This makes the code a lot simpler and fixes a bug where we
could accidentally stop restylying for very delayed restyles.
Add an internal API that allows GtkStyleContext to create a widget path
for the widget and with that bypassing gtk_widget_get_path() and that
function caching the path.
Include the child widget path in the returned path now. This allows
customizing the path of the current widgets - like adding flags to child
widgets (and maybe siblings in the future).
This commit simply removes some child->parent == container checks,
to add some flexibility for containers with 'inner structure'.
If these checks are considered useful, we can bring them back
with a is_child vfunc that allows container implementations to
decided who they consider legitimate child.
This is a variant of gtk_widget_child_notify() that takes an
explicit container, instead of relying on widget->parent to
be the correct container to use.
The constant size request mode defines a request mode where
height-for-width geometry is unneeded, thus optimizing GTK+
by reducing the overall amount of requests that need to be
performed and cached while resizing an interface.
