For performance reasons, resources required to paint a widget are
aggressively cached; we know of at least one case where our caching
prevents updating the used background-image correctly, so add explicit
API to clear all associated cache data.

Since the invoker for navigate_focus has an extra parameter, annotations
from the invoker aren't applied on the vfunc itself. Fix that by annotating
the vfunc separately.
Since we want to paint children by default in StWidget, we need to
provide a way for custom subclasses to paint their CSS backgrounds
without painting children... introducing st_widget_paint_background.
Additionally, remove any custom paint/pick handlers added by subclasses
of StWidget that just painted their children. This will cause double
painting if left alone.
This also removes the hacky things that some subclasses of StBin did
to prevent their one child to be painted by StBin.

We can't get rid of the implementations in StContainer just yet,
as StContainer still keeps its own child list. But this should
lower the amount of code that has to be moved around when we
remove StContainer.

This property represents that the widget is being labelled by an
actor. The name is label-actor to avoid problems with the current
StButton:label and StTooltip:label
Inside the Shell, all the UI (including chrome, the overview, and
the actual windows) is not a child of the stage but of a special
ClutterGroup, which is cloned inside the magnifier.
Add function for setting this special actor so that actors added by
St are visible in the magnifier. Nothing yet uses this, but the
tooltip will soon.

It includes:
* Expose a proper focusable state, instead of the default one from
cally, using StWidget::can_focus, and also notifying the state change
* Management of the selected stated, using the current pseudo_class.
* Defines a new virtual method on StWidget: get_accessible_type. In
this way it is not required to reimplement get_accessible just for
a accessible type change. get_accessible is reimplemented using this.
You can see that as a substitute of the atk object factory

Sometimes it's useful to get the theme node if there is one and do
nothing and wait for the ::style-changed signal if there is no theme
node. Add st_widget_peek_theme_node() that just gets the current
theme node if available. The caller must handle a %NULL return.

* Make sure all source files have a LGPL copyright header, and standardize
non-standard variations of the header to a common form.
* Check and update all copyright notices.
* Remove 'Written By:' lines. They are universally incomplete and
typically indicate only who started a particular file.

Add StWidget:can-focus, st_widget_navigate_focus(), and
st_container_get_focus_chain(), and implement as needed to allow
keyboard navigation of widgets.

It has probably crossed the line to evil by a mile or so, but here
it is: a Tweener.slowDownFactor replacement used by all animations
without exception.
While at it, update Tweener to use the new setTimeScale() upstream
function instead of adjusting the timeline directly.
https://bugzilla.gnome.org/show_bug.cgi?id=622249
If track-hover is set, update the hover property automatically, and
the "hover" pseudo class to match, as StClickable used to do. (Remove
the corresponding code in StClickable). Tweak the tooltip handling to
use track-hover, which also makes it slightly more reliable in the
presence of reactive children, etc.
Since style_class and pseudo_class are space-separated lists of names,
add new methods to add and remove individual names rather than just
re-setting the entire name.
Update existing code to use the new pseudo-class methods where
appropriate. In some cases, this may result in actors having multiple
pseudoclasses where previously they only had one at a time, but there
don't seem to be any visible differences.
(There are some places that could usefully use the new style_class
methods as well, but this patch doesn't change them.)
Also, update test-theme.c to test the new methods.
https://bugzilla.gnome.org/show_bug.cgi?id=604943
StButton animated the background for button transitions; since these aren't
presently part of the shell design, simply remove them. We can readd
these in the future.
StTooltip should probably have :vertical and :horizontal pseudo classes
to make the arrow work but it should still function.
https://bugzilla.gnome.org/show_bug.cgi?id=607500
Use BigRectangle to draw the border and background if there's
a border width or border radius and no border image. (Only
uniform borders are supported for now with some deviations
from the CSS model noted in the comments.)
The background color and image parameters are removed from
StWidget's draw_background() method since they were not used
for StButton (the only current user) and the encapsulation
break that they presented caused some minor problems.
Add a test case for borders, and also use borders to style
the buttons in the 'inline-style' test case.
https://bugzilla.gnome.org/show_bug.cgi?id=595993
Rather than repeating the computation of borders in many different
widget subclasses, add helper functions:
st_theme_node_adjust_for_height()
st_theme_node_adjust_preferred_width()
st_theme_node_adjust_for_width()
st_theme_node_adjust_preferred_height()
st_theme_node_get_content_box()
That are used in get_preferred_width()/get_preferred_height() and
allocate() methods to consistently apply the necessary adjustments.
This allows removing the StPadding type.
Queueing a relayout when the borders/padding change is moved from
st_widget_real_style_changed() to the invoking code to allow access
to the old StThemeNode for comparison. (Should this be added as
a parameter to the signal?)
Borders are included in the geometry adjustments, but borders
are not yet drawn.
https://bugzilla.gnome.org/show_bug.cgi?id=595993
Add support for passing an inline-style string when creating a
StThemeNode.
Hook this up to a new 'style' property of StWidget.
Add a test case that demonstrates using this to update font sizes
on the fly.
https://bugzilla.gnome.org/show_bug.cgi?id=595991
ShellTheme replaces both StStyle and ccss_stylesheet_t.
The interface StStylable is replaced by usage of ShellThemeNode.
A concrete node class allows some significant optimizations of property
inheritance that would have been much more difficult to achieve with
the highly abstract pair of StStylable and ccss_node_t.
Some operations that were previously on StStylable (like the
::style-changed signal) are directly on NtkWidget.
Custom properties are no longer registered as param-specs; instead you
call directly into shell theme node to look up a length or color:
shell_theme_node_get_length (theme_node, "border-spacing", FALSE, &spacing);
The dependency on libccss is dropped, while preserving all existing
functionality and adding proper parsing and inheritance of font properties
and proper inheritance for the 'color' property.
Some more javascript tests for CSS functionality are added; workarounds for
a CSS bug where *.some-class was needed instead of .some-class are removed.

To each .c and .h file, add:
/* -*- mode: C; c-file-style: "gnu"; indent-tabs-mode: nil; -*- */
'gnu' is the default anyways for Emacs, but indent-tabs-mode is not,
so this sets things up to correspond to the policy of no-tabs.

Import the core MxWidget/MxBin and their dependencies; we use the
namespace "St" (Shell Toolkit) because it is the same length as Mx
so enabling easy sharing of code, but makes it clear that this is
a friendly fork and not a literal import.
