There's no reason to insta-crash when something goes wrong. Just don't
do anything stupid.
Also, remove the SPCIAL_CONTAINER() exception. Every case where special
containers needed this, it is wrong and made containers draw children
multiple times.
GtkShortcutsWindow is among the 'cheating' containers that iterate
over indirect children in forall, and this is now triggering
an assertion in gtk_container_propagate_draw.
For now, just exclude the cheating containers from the assertion.
Eventually, this needs a better solution.
gdk_rectangle_union will happily add all the worlds pixels
to the union if the initial rectangle is initialized to all
zeros. Therefore, explicitly check for an empty rectangle
before calling it.
Previously, we had a special cae to draw subwindows of widgets.
This is not necessary as conformant widgets should be able to properly
render themselves when all windows need to be painted.
From now on assume that is the case.
We therefore paint nonnative GDK windows "inline" by just returning TRUE
for gtk_cairo_should_draw_window() for those windows.
This speeds up hilighting different rows in the listbox gtk-demo example
tremendously (by a factor of 10 or more) as the previous code was
O(<number of non-window subwidgets> *
<number of subwindows>) which in the listbox example were ~15,000 and
~2,000 respectively.
This commit toggles the big switch. We now don't run size_allocate()
from the toplevel up anymore in cases where we don't need to.
Things might be broken in subtle ways as a result of this commit. We'll
have to find them and fix them.
We were calling gtk_container_should_propagate_draw
twice for each child. We can avoid this by splitting
out an gtk_container_propagate_draw_internal function.
This reverts commit 3eacfa88f2.
Apart from the patch not being correct, we don't want to expose private
structures in header files if we can avoid it.
And this type-checking overhead is not an optimization that is even
measurable.

Instead of issuing g_warning, fill the provided GError.
This lets us test this error handling, and is the right
thing to do. Use the new GtkBuilder helpers and
g_markup_collect_attributes to do so.
- 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.
