988a0e7314 Adapt to painting and picking API change
While still leaving them unused, pass around ClutterPaintContext and
ClutterPickContext when painting and picking.

The reason for splitting this change up in two is to make it possible to
bisect easier in between the API change and the change to using the
framebuffer passed around with the temporary contexts.

55867c40c4 st: Drop StWidget theme overriding API
A StWidget could get its style from a) a theme set in the StThemeContext,
and b) directly through it's ::theme property. Generally, overriding CSS
through the latter cannot be recommended as it loses any connection with
the global theme (eg. the ones you get through selector specificity).

It sounds a bit too powerful and pervasive, there's no use for it in
gnome-shell and doesn't look like something that could be recommended on
extensions. So, just drop this piece of API.

9f4ae9618a st-widget: Introduce widget resource scale
This commit makes StWidget manage the scale of which its associated
resources should be multiplied with. The resource scale is calculated
by clutter, and is retrieved by clutter_actor_get_resource_scale(). Due
to the resource scale not always being available, the getter may fail,
and the actual widget that draws the content will have to deal with
this situation.

As the resource scale depends on where on the stage the widget is drawn,
the resource scale will in general be available once the widget is
mapped.

c59c5eb893 st: Add StDirectionType enum
In order to replace GTK+'s GtkDirectionType. It's bit-compatible with it,
too. All callers have been updated to use it.

ffe4eaf00d st: Use G_DECLARE_*_TYPE
Cut down on boilerplate by using the (no longer that) new helper
macros. We don't care about breaking ABI in private libraries, so
use G_DECLARE_FINAL_TYPE even where the class struct used to be
exposed in the header, except for types we inherit from ourselves
(obviously) or where the class exposes any vfuncs (where changes
could affect inheritance in extensions).

bd28d5c48a a11y: add the possibility to set the accessible object of a widget
In the common case, the accessible object is created by the
own widget. In some cases it is needed to specify a custom
accessible, as some of the logic will be implemented on the
javascript code (extend functionality using Components vs Hierarchy).

64b2c5d1b4 st-widget: Add a proper paint, add st_widget_paint_background
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.

125adb4d32 StWidgetAccessible: accessibility support for StWidget
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

node. Add st_widget_peek_theme_node() that just gets the current
theme node if available. The caller must handle a %NULL return.

If track-hover is set, update the hover property automatically, and

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.

909b5ec43c [StWidget] add list-like methods for style_class and pseudo_class
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.

2a0adc0fc8 Add support for colored borders
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.

076e902b2c Centralize computations of border and padding into StThemeNode
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.

a9fd350396 Port our imported parts of Mx to ShellTheme
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.
