9420174477 st-scroll-view: Remove some dead code
This assignment was shadowed by the giant switch above. Since the
switch has a comment or two explaining the logic inside of it,
keep that instead of the assignment.

fd4d645687 st-scroll-view-fade: Add horizontal fade support
St-scroll-view-fade only allowed adding a fade effect in the vertical
direction; extend it so it can work horizontally too.

15f881f967 st: Remove custom text direction stuff
Clutter has its own built-in system for managing text directions, like GTK+.
Convert over to use this.

ea19790828 st-widget: Implement a proper allocate
Since an StWidget now has children, it needs to allocate those children
properly. Defer to the currently installed layout manager, like Clutter
does.

Now that we have something that allocates children in St, to prevent
double allocations, we use clutter_actor_set_allocation rather than
chaining up to StWidget::allocate.

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.

e7289378b7 st-scroll-view: Make the fade effect and offset themable
Theme authors now have the power (and responsibility) of creating fade
effects with the new CSS length property '-st-fade-offset'. A value of
0 disables the effect.

This new CSS approach replaces the current programmatic toggle of
the 'vfade' property. A new CSS style class name 'vfade' is used as
a replacement for the old property.

ce72aaf008 Fix up copyright and license notices for St
* 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.

b856e2990b StScrollView: null out the right variable in dispose
We weren't properly nulling out the vadjustment variable in dispose()
which meant in the case of explicit-destroy followed some time later
by garbage collection and disposing the actor again we would crash.

89173544d4 Simplify handling of adjustments
The relationship between adjustments and scrollbars and
scrollable widgets was much more complex than it needed to be.

StScrollView: Have the scroll view own a pair of adjustments,
  set them on the child on add(), remove unnecessary
  change notification signal connections.
StBoxLayout: Remove auto-create of adjustments, just take the
  adjustments from the scrollbars and set them on the scrollable
  child. Notify for hadjustment/vadjustment properties.
StScrollBar: Notify adjustment property.
StScrollable: Document how adjustment setting works.

c83883f1f7 Fixes for setting up scrolling adjustments
StScrollable: Document how to set adjustments
StBoxLayout: Make sure that we always have upper >= lower + page_size,
  so that clamping works properly. Set the page_increment to be slightly
  less than the page_size so there is some overlap, as is customary.
StScrollView: Remove unnecessary fabs() calls, rewrite expressions
  for additional clarity.

f6cbb14393 Incremental fixes for scrollview work
- Fix existing typos and spacing problems
- Get preferred height, not current height, of shadows
- Let shadows overflow don't clamp them when we have too little space
- Remove a now-unecessary stray MAX()
- Fix up scrollview visibility for the pathological case of no child
- Disconnect from adjustments on remove()
- Don't unset the adjustments on the child on remove(), since they
  already existed or were autocreated on add()

  (We should what we are doing and set the adjustments of the
  scrollbars on the child rather than setting the adjustments of
  the child, so we match GTK+'s scrolllable interface, but this
  at least makes it consistent instead of a weird mix.)

ffd25fe9e4 Fix size negotiation for StScrollView
StScrollable: Document how size negotation now works between the
  parent and scrollable child.

StBoxLayout: Adapt to the new contract for how size negotiation
  works; in particular, handle being allocated less than the
  minimum size when scrolled and treat the minimum size as the
  size of the scrolled area in instead of the natural size.

StScrollView: Substantially rewrite with fixes including:
 - Implement new size negotation contract; this allows us
   to determine scrollbar visibility without having to
   connect to the adjustment.
 - Implement all ALWAYS along with the existing NEVER/AUTO
 - When hiding and showing scrollbars and shadows, don't
   hide and show widgets, just turn on and off including them
   in pick and paint. This avoids queueing relayouts.
 - Cleanups for the code for connecting to adjustments,
   for changing policy, and for turning on and off shadows.

scroll-view-sizing.js: New test case for StScrollView, allowing
  resizing the scroll view interactively, changing the scrollbar
  policies and turning shadows on and off.

6423cbfc92 Fix problems on destruction
StScrollBar: Be robust against being disposed multiple times,
  which can happen, and in fact, normally happens when destroying
  the parent.

StScrollView: Implement remove() for the hscroll and vscroll members,
  and just destroy them in dispose() and let them be removed.
  unparent the shadows, instead of just unref'ing them directly.

fb9fd6925a [StScrollView] Fix incorrect assertion, defaults, and test case
The type we don't currently handle is _ALWAYS, my original use
of g_return_if_fail was wrong.

Also the default should be AUTOMATIC in the properties, not ALWAYS.

Finally the test case was still using the incorrect St.ScrollPolicy.

18c5405b79 [StScrollView] Add support for GtkPolicyType for scrollbars
Previously we were hacking out the vertical scrollbar, this patch
allow us to sanely say in which directions we want to scroll.

Note this patch intentionally changes St to depend on GTK+ in the
API.  I believe this is a correct long term change where we should
view St as co-evolving with GTK+ rather than replacing or paralleling.

ab0460ad59 Use clutter_actor_destroy in dispose, add _dispose where needed
ClutterGroup calls _destroy, but most of St was just calling _unparent.
This caused problems because the DESTROY signal was not emitted
for child elements after destroying a toplevel.  Also, in a GC'd
binding it would cause unpredictable lifetime of children.

Some St widgets simply didn't have _dispose at all; implement it.

Note because of the usage of the background_image in StButton,
we can't cleanly destroy it inside the StWidget.

a15205e6c4 Fix interaction of borders/background and scrolling
StBoxLayout: Make consistent that the area scrolled and clipped
to is the content area (excluding borders and padding.) Translate
back appropriately when chaining up so that the parent background
is drawn at the right place and picking on the box (if it's reactive)
picks at the right place on the screen.

clip-to-allocation is removed from StScrollView since it's just
not right - if the child has any non-moving elements, like headers or
borders, it will need to set a narrower clip. And even if the entire
child scrolls, we want to clip to an arrow that excludes the scrollbars.

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.

e91e8e993d Add emacs mode-lines to ST sources
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.

st_texture_cache_get_actor() and st_texture_cache_get_texture()
