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.
The gtk_label_set_text() and gtk_label_set_markup() functions have
various side effects that ought to be documented, especially for
non-C developers using properties directly.

Instead of drawing text for selections and links manually, use the
gtk_render_background() and gtk_render_layout() functions.
As a side effect, this allows shadows on selected text and links
and real backgrounds (like gradients or images), too.
Since it turns out that x/yalign can't be quite equivalently
replaced by h/valign, bring them back as label properties, so
we can eventually get rid of GtkMisc.

When links are entirely hidden in an ellipsis, don't let
them be activated by clicking and skip them when moving
the focus around.
This commit depends on enhancements in pango 1.36.7 which
make it possible to find the ellipsed runs in a PangoLayout.
With older pango, things will work the same way as before.

GtkGestureSingle::button is set to 0 on the multipress gesture, as several
buttons are managed by that gesture. Also avoid some extra lines of code
setting what nowadays are default values.

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.
Otherwise, the CSS background we draw would be clipped if the ink rect
was smaller than the allocation (a very common thing).
Broken since 37030a7710 where we clipped
to the ink rect.
A multipress gesture takes care of link handling, and char/word/all
selection mode on selectable labels. A drag gesture is used for both
text selection and DnD checks on selectable labels.
Go back to respecting GtkMisc::xpad/ypad. Not doing so breaks
the misc-alignment reftest. As long as we still derive from
GtkMisc, we may as well do this.
We see an active link when creating the menu, but by the time
the menuitem is activated, we've received a leave notify that
makes the label clear its active link. Instead, give the
menuitems a direct reference to the link that is active when
the menu is created.
Problem pointed out by Tim Baedert
gnome-terminal is still using this setting, so we'll let
applications override it for another cycle. It is no longer
backed by a system-wide setting, though, and it will still
go away eventually.

We should only eat button release events when the label is
actually selectable, since the comment indicates that we
want to eat the release events belonging to press events
that triggered a selection. This fixes problems with actions
on parent widgets that are triggered by button release,
as seen in this bug:

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.
This commit makes the label accessible implement AtkHypertext,
which returns a AtkHyperlink object for each link in the text.
At the same time, add AtkHyperlinkImpl objects as children
to the label accessible.
Also some private API to indicate that links have changed, and
call that from GtkLabel when needed.
Adjust expected output of the affected a11y tests.

When setting the lines property, the label will be ellipsized
to that many lines, with the ellipsis only appearing in the
last line. This is different from how ellipsization of multi-line
labels normally works in GTK+.
Attached widgets inherit from the style of the widget they are
attached to. This can sometimes have unintended consequences,
like a context menu in the main view of gedit inheriting the font
that is configured for documents, or the context menu of the preview
in the font chooser coming up with humongous font size.
To fix this problem, we introduce a context menu style class
and use it for all menus that are used like that. The theme
can then set a font for this style class.

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.

We've recently a number of classes wholly. For these cases,
move the headers and sources to gtk/deprecated/ and adjust
Makefiles and includes accordingly.
Affected classes:
GtkAction
GtkActionGroup
GtkActivatable
GtkIconFactory
GtkImageMenuItem
GtkRadioAction
GtkRecentAction
GtkStock
GtkToggleAction
GtkUIManager
To extract the mnemonic key value, the string must contain the
underscore. But when the "gtk-auto-mnemonics" setting is true and when
the Alt key is not pressed, the underscore must not be displayed. The
problem was that the 'new_str' variable was used for both purposes:
extract the text to display, and extract the accelerator character.
When the underscore must not be visible, the underscores were removed
from the 'new_str' variable before extracting the accelerator character.
Now there are two strings, one for each purpose.

When setting new text on the label, the text-changed::delete signal
needs to be emitted before deleting the text (so that atk-bridge can
query the old text) while the text-changed::insert event needs to happen
afterwards (for the same reason). The old code using the notify signal
was only emitted after changing the text.
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.

Now that Pango tracks changes to the context automatically there is
no need to do it manually in e.g. style-updated or direction-changed,
in fact the only case we have to care about is when we re-create
the PangoContext due to a screen change, so we only have to clear
the layouts in GtkLabel in screen-changed.
This means we're not clearing all the layouts whenever the state changes,
which happens to every widget when the window is unfocused, which helps
performance a lot.
https://bugzilla.gnome.org/show_bug.cgi?id=340066
Instead of using gtk_style_context_get_font() in
pango_context_get_metrics(), use pango_context_get_font_description().
The context contains the font description we are about to use after all.
If the "wider" label is the smaller one, use the wider size for both
cases. This can happen when ellipsizing a single character, which is
often smaller than the ellipsizing glpyph(s).
With ellipsizing, the ellipsized text can have a smaller height than the
non-ellipsized text. So the wider text is also higher. Example:
.<big>TEXT</big>
will ellipsize to the small text.
Reported-By: Rico Tzschichholz <ricotz@t-online.de>
The label code assumed that Pango treats this as "wrap to as much space
as possible and then ellipsize all the lines", but for Pango, ellipsize
takes precedence over wrap. So do the same thing in GtkLabel.
Also updated is the reftest that checked this behavior.
When we are re-setting the same text for internal reasons
(e.g. when applying the mnemonics-visible change upon Alt press),
we should not needlessly loos the selection.

The new semi-private function will allow to implement support for css
padding and border in widgets inheriting from GtkMisc.
Use the new function for GtkLabel, GtkArrow and GtkImage.
Instead of "attribute with later start index wins, make sure the
attribute list that is merged from takes precedence. This now gives the
multiple attribute lists we use in the label an order:
1) gtk_label_set_attributes()
These attributes override everything. It's what the function's there
for after all.
2) markup of label
Other user-specified attributes come next.
3) attributes for links
When we apply custom attributes on parts of the text, we put them
last. We don't want to mess with what the user does. Also, we change
color and underline, so we usually have something to show.
- Don't compute link color attributes until layout creation
This is useful as a performance enhancement, because we don't have to
lookup the property after setting the text, so multiple markup sets
don't cost style lookups.
- Don't merge attrs into effective_attrs
We do this when applying link colors now. Keeping them separate allows
invalidating them separately.
Instead of getting confused by applied underline or color tags in the
regular markup, we store the link start/end when we actually parse the
text. As a bonus, we can avoid rescanning links when creating the
markup.
The new function provides an API that takes the PangoLayout and index
as input params, this way it handles strong and weak cursors internally
factoring out all code duplicated in the widgets that need to render
cursors.

Add _gtk_button_event_triggers_context_menu() and use it instead
of checking for event->button == 3, so context menus are invoked
correctly on the Mac.
