Add a 'vshadow' property to StScrollView, which, when turned on,
overlays gradient shadows on the top and bottom of the StScrollView.
Turn this on for the StScrollView used for the app browser.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=609015
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.

st_theme_node_adjust_preferred_width/height now limit the content area
of an actor to the max, if given. (The requested width/height may be
larger to make room for borders, etc.)
https://bugzilla.gnome.org/show_bug.cgi?id=606755
In StBin, StBoxLayout, and StTable, if a child has a potential
allocation that is larger than its preferred size, we give it its
preferred size instead. However, the corresponding
get_preferred_height/width methods were not making the same
assumption, which meant that if we had more width than the widget
wanted, we would allocate it its preferred width, but with the height
that corresponded to the larger width.
Fix this by defining new helpers _st_actor_get_preferred_width() and
_st_actor_get_preferred_height() and using them everywhere. Also, make
StBin and StTable use _st_allocate_fill() rather than having
nearly-identical duplicate copies of the code.

The forward/backward steppers are always allocated a square region at the
scroll bar's ends. Change the allocation to be based on the steppers' size
requests instead.

To comply with C89, structure initializers should have
only constant values.
(Not a thorough check for this throughout the codebase, just
StWidget is fixed up in this commit.)
https://bugzilla.gnome.org/show_bug.cgi?id=608746
By calling clutter_actor_get_allocation() in st_widget_recompute_style()
to determine whether to redraw gradients, we triggered a complete
reallocation of the stage for each gradient.
As gradients are processed in st_widget_real_style_changed() anyway, the
additional checks in st_widget_recompute_style() are redundant and can
be removed altogether.
https://bugzilla.gnome.org/show_bug.cgi?id=608847
On style changes from gradient to solid backgrounds, the new background
must be drawn unconditionally, not depending on whether old and new
background color differ.
https://bugzilla.gnome.org/show_bug.cgi?id=608914
When moving a widget with a gradient, its allocation changes
continuously, resulting in constant redraws.
Checking for actual size changes before the operation avoids
unnecessary redraws.

StButton has an internal animation for the border-image actor, then
it connects to the "completed" signal passing itself as data. However,
if the button is destroyed, nothing prevents the animation's completed
signal from then causing a reference to freed memory.
Holding a reference to the button is the most straightforward fix here.

Some theme authors have stated interest in radial gradient backgrounds.
The w3c has some draft:
http://dev.w3.org/csswg/css3-images/#radial-gradients
As this is rather complex, we add only some very basic support, which
extends our syntax for linear gradients:
background-gradient-direction: [vertical|horizontal|radial]
Gradients are centered circles, whose size is determined by the closest
side.
https://bugzilla.gnome.org/show_bug.cgi?id=604945
Some changes to the way we handle CSS gradients:
* draw without padding, thus interpreting gradients as part of the
background rather than as content
* clip to (rounded) border area
* draw the border along the gradient instead of trying to align the
gradient layer with the background/border layer
* use the border_image actor instead of the background_image one
https://bugzilla.gnome.org/show_bug.cgi?id=606257
Add support for a new -st-shadow property, which is based loosely
on the CSS3 box-shadow property:
http://www.css3.info/preview/box-shadow/
It defers from the specification as follows:
* no multiple shadows
* the optional color argument may be placed anywhere
* the shape is not determined by the widget's bounding box,
but by the background-image property
https://bugzilla.gnome.org/show_bug.cgi?id=603691
Move CSS handling of StLabel and StButton for their underlying
ClutterText objects into st_private, and implement support for
the underline and strikethrough St text-decoration properties.
Overline isn't implemented for lack of a corresponding Pango
attribute, and blink, well...
https://bugzilla.gnome.org/show_bug.cgi?id=599661
Now a StBin, and add hover/active style properties. Also, add the
event to the CLICKED signal. Otherwise a straightforward namespace
transformation.
https://bugzilla.gnome.org/show_bug.cgi?id=602131
It's nicer to have ShellDrawingArea as a St widget so it can
participate more cleanly in CSS styling, such as queuing a redraw
automatically on style changes, and allowing subclasses to use
CSS styling.
https://bugzilla.gnome.org/show_bug.cgi?id=602131
Rather than having gradients be individually implemented by higher
level JS widgets, move basic gradient functionality into StWidget.
There is prior art in WebKit for CSS gradients:
http://webkit.org/blog/175/introducing-css-gradients/
However, implementing this would be quite a lot of work; all we
need in the Shell design at the moment is basic horizontal/vertical
linear gradients. So, the syntax now supported is:
background-gradient-type: [vertical|horizontal]
background-gradient-start: color;
background-gradient-end: color;
https://bugzilla.gnome.org/show_bug.cgi?id=602131
An earlier commit was overzealous in removing (out) annotations;
introspection supports (out) for integral types just fine, we
only need to remove them for (out) types where the caller needs
to allocate a boxed type.
https://bugzilla.gnome.org/show_bug.cgi?id=602131
In a variety of places we're using boxes as data-modeling displays,
and in doing so we often want to either remove the children or
explictly destroy them.
Now ideally Gjs would support callbacks, and this would make using
the for_each functions possible, but even then these functions
are more efficient and shorter to type, at least.
https://bugzilla.gnome.org/show_bug.cgi?id=600734
If the space we're allocated is too small for our border + padding
constraints, don't give negative allocations to callers. Squash
to zero.
It isn't really useful for callers to get negative content sizes,
and certainly breaks most allocation code.
https://bugzilla.gnome.org/show_bug.cgi?id=600734
StTheme CSS supports different border widths for different sides. Implement
it for StWidget by drawing the border internally. However, we don't support
a nonzero corner-radius with nonuniform borders.
https://bugzilla.gnome.org/show_bug.cgi?id=599442
The behavior in respect to borders matches CSS - the properties set the size of
the content exclusive of the borders (CSS3 box-sizing property - not implemented
here - changes this).
min-width/min-height correspond very closely to the CSS meanings.
width/height are a little different from the CSS meanings - the CSS meaning is
"exactly this size unless overridden by min/max-width/height" - but within the
realm of our layout algorithm, making them control natural size is pretty
close.
This way we can force elements to have a fixed natural or minimum size.
https://bugzilla.gnome.org/show_bug.cgi?id=598651
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.
https://bugzilla.gnome.org/show_bug.cgi?id=597845
Add StIMText, which is a drop-in replacement for ClutterIMText but
uses GtkIMContext instead of ClutterIMContext.
StIMText doesn't have preedit support (would need ClutterText
changes), so isn't going to be useful for complicated input methods,
but is good enough to get dead keys and similar working.

To work around a problem where libcroco < 0.6.2 can't handle
functions starting with 'r' or 'u', preconvert 'rgba' to 'RGBA'
when parsing stylesheets and then check for rgba()
case-insensitively.
(libcroco is uniformly case-sensitive, though the CSS spec requires
that ASCII should be handled case-insensitively.)
https://bugzilla.gnome.org/show_bug.cgi?id=597054
round() is a C99 addition, so causes portability problems:
different C library versions require different #defines to
enable it. So simply avoid using it.
Property enumeration names should correspond exactly to the property names;
in particular the ACTIVE vs :checked disparity was confusing reading the
code.
