An animation may be scheduled while the textview content changed in size, so the resize
queued would just unset the animation and set the adjusments with a current value,
defeating gtk_text_view_scroll_to_iter(). In this case, just avoid the adjustment change,
as there is a target value on the way.

Popovers may get relocations optimized away if only x/y changed
in the GtkAllocation. So make sure the toplevel updates popover
positions on all situations.

It is bad if the image that is used as a fallback for missing
images goes missing itself, so include it as a resource. This
way, it will always be available.
The rules-hint property has always been a fairly bad application API, as
it set some wrong expectations for the developers; deferring to the
theme makes it impossible to design application reliably, and if this is
a usability setting we should either impose this setting on every theme,
or simply drop it.
Our own default theme does not honour the zebra striping, which makes
this function even more questionable.
In practice, usability studies on zebra striping have demonstrated that
alternating colors on a list it improves readability just as much as
clear ruling between rows, or by visually differentiating the selected
row. Zebra striping improves readability (or, at least, it does not
hinder it) on static displays, like a table on paper or a document; on a
dynamic display, like an application's UI, there are different
strategies that yield similar, if not better, results.

The next call to gtk_list_box_get_selection_mode just expected the
GtkListBoxRow's parent to be a GtkListBox and failed when the row was
added to something other than a GtkListBox.

If an icon theme has a file called "foo-symbolic.symbolic.png" which
was converted from svg using gtk-encode-symbolic-svg we will read
it in an recolor, allowing symbolic icons without using librsvg.

If the same position is requested on a popover, it should at least ensure
the window is realized and raised, even if no resizes are queued on the
content. Otherwise other widgets being mapped might raise the windows over
the popover's if its original position is unchanged.

It turns out that when we were painting the shadows, we painted the them
with the base color once, which contained the alpha, and then blurred it
and used it as a mask for the fill, which has the fill again.
To fix this, always paint the base surface with full alpha. The existing
code applies the blur conditionally sometimes in weird ways, so the code
shuffling fix may not look correct, but be assured it is. If the blur
happens, the new cr we return has the *default* color applied, which is
fully opaque black, which works perfectly against the A8 surface.
The fallback spinner code needs some modification, since it is
intentionally using the alpha to paint the lobes which are "in the past".
Since we shouldn't be hitting this fallback path very often, we use a
temporary group and paint it with paint_with_alpha, even though it is
slow.
Introduce a new debug category "actions" and write some messages from
GtkActionHelper about if we can find the actions or not.
We will probably soon want to add some similar messages to
GtkMenuTrackerItem.

This leads to an assertion failure, because parent window is never registered
in the first place, widget's own GdkWindow is. But that window is unregistered
in a generic fashion by GtkWidget code, so there's nothing for us to do here.

So far, gtk_window_set_focus just did not work when called on
a hidden window. Change it to record the desired focus widget
for hidden windows, and apply it when the window gets shown.
This is similar to how we tread other window properties that
can't be set before the window is realized, like maximized
or fullscreen.

The previous code for computing the clip rectangle forgot to respect
the text-shadow CSS property. This is usually not very visible because
text shadows usually don't extend the ink rectangle by very much.
See attached testcase for an example.
Although there is the "changed" signal, it is more correct to notify the
"text" property too. It can be useful for a small text view, where the
text is saved e.g. to gsettings with a binding to the text property.
The "text" property includes only the text, not child widgets or images,
so the notify signal is sent too many times (also for child widgets and
images), but it's not a big problem.

Currently, when loading an image from a GResource or file we don't take
the scale factor of the display into consideration, and let
GtkIconHelper scale it accordingly.
While this in general works for non-scalable images, we can take
advantage of the native loader's scaling for e.g. SVG images, and load
them at the right scale factor automatically.
This is achieved by switching to a pixbuf loader instead of using the
native function.

This allows subclasses to render things below and above the text
in the text view. This allows e.g. GtkSourceView to highlight the
cursor row and to render overlays for colum 80. This used to be done
by rendering before/after chaining up to the parent, but that doesn't
work anymore since the view now renders a background, and due to the
use of the pixel cache.
This reverts commit 1ac13435b7.
We want to instead replace this with special vfunc for drawing
below/above the main text so that gtksourceview can use it.
This was silently broken - the code was just assuming that the
text cell renderer is item no. 6 on the list of all cells. That
doesn't work so well if the cell renderers are set up elsewhere
and get rearranged.
Fix this by keeping an explicit pointer to the the text cell.
For images without a concrete size but with an aspect ratio, we took the
wrong code path.
(I even copied the documentation that said "Otherwise" but didn't put an
else clause there, go me!)
Now that widget paths are allowed to have a state, use that state when
querying style properties. This uses a fast path in gtkcssprovider.c and
that is great.
Header-bar and action-bar buttons used to be bigger then others
now everything is as big as those, maintaining two different sizes
for default widgets depending on the placement is a maintainance
nightmare and having controls the same size is good from a usability
point of view.
The toplevel_window was never set, and the only place where it
was used was causing us to hide tooltips needlessly. So removing
it is a double win.

Add yet another tab for showing information about a widget that
does not quite fit into any of the other tabs (not a property,
not style information, etc...).
For now, we show the widget state, as well as the default and
focus widget for windows.
GtkArrow is deprecated and is not used internally anymore by the
menu button. Document also the fact that if no direction is specified
then the view-context-menu icon is shown.

People expect to be able to call gtk_widget_show_all on the dialog
to make action widgets visible, as seen e.g. in
https://bugzilla.gnome.org/show_bug.cgi?id=733431
To keep this working, we can't always set no-show-all on the
action_box. Only set it when the action_area is not used and empty.
The accel label in menus was getting a small allocation that
caused its draw code to always omit the accelerator string.
Fix that by setting halign to fill. To keep the menu label
left-aligned, set xalign to 0 to compensate.
Make gtk_widget_path_append_for_widget() add the state flags of the
widget, too.
This enables the ability to select pseudoclasses on all elements in a
selector.
