52768ee6ec stylecontext: Deprecate direction property
...  and the functions implementing it. Also deprecate the direction
getter on GtkThemingEngine.

a73cc55e02 stylecontext: Use state flags for direction
... instead of using a custom direction member.

And with that, GtkWidget doesn't need to call
gtk_style_context_set_direction() anymore.

5e12aafacd stylecontext: Fix gtk_style_context_set_background()
This function is just a sophisitcated optimization.

If we know the GDK window's background will be opaque, we mark it as
opaque. This is so GDK can do all the optimizations it does for opaque
windows and be fast.

This is mainly used when scrolling.

The previous code didn't get this right, in particular it didn't enforce
a transparent background when it knew the background was not opaque.

9ae9649188 stylecontext: Deprecate gtk_style_context_get_font()
This is for a very simple reason: The getter is returning a const value
and the font isn't const anymore. So we need to store the font
description somewhere but we can't reuse it as it's changing all the
time (yay animations, yay inherited values). Sucks.

So keep the hack in here but deprecate the function.

732e89e4f3 stylecontext: Always recompute font
This is necessary  because values in a GtkCssComputedValues can change
now. So if the font-size is inherited or animated, the cached value will
be outdated.

Fixes the fontchooser preview not updating.

fb643c1c12 symboliccolor: Deprecate
Symbolic colors are an implementation detail of the CSS engine and have
been superceded by GtkCssColorValue. We don't want them clobbering the
public API. In particular because the only use I could find in the
public API is people using it to shade colors.

42dc0ea0fd styleprovider: Change function prototype
Make _gtk_style_provider_private_get_color() return a GtkCssValue (a
GtkCssColorValue to be exact) instead of GtkSymbolicColor.

With this, the symbolic color usage inside GTK is minimized.

6d3b4d9382 stylecontext: Add a flag to force style_updated() emission

55d65571f3 Exit early in gtk_style_context_update_cache codepaths
If lookup->missing is empty we don't need to continue looking.
We short circuit in several places as this can happen
after iteratively makeign lookup->missing smaller.

16677bb85a stylecontext: Don't use bg image in gtk_style_context_set_background()
Old code tried to use the "background-image" proeprty for setting the
default image background. While this used to work in the early days of
GTK3, today it is grossly misleading as the backgronud image may be
resized, repositioned and semi-translucent which causes very weird
artifacts when rendering.

So we use the background-color only instead.

1454ba15ba css: Huge refactoring to avoid computing wrong values
Here's the shortest description of the bug I can come up with:
When computing values, we have 3 kinds of dependencies:
(1) other properties ("currentColor" or em values)
(2) inherited properties ("inherit")
(3) generic things from the theme (@keyframes or @define-color)
Previously, we passed the GtkStyleContext as an argument, because it
provided these 3 things using:
(1) _gtk_style_context_peek_property()
(2) _gtk_style_context_peek_property(gtk_style_context_get_parent())
(3) context->priv->cascade

However, this makes it impossible to lookup values other than the ones
accessible via _gtk_style_context_peek_property(). And this is exactly
what we are doing in gtk_style_context_update_cache(). So when the cache
updates encountered case (1), they were looking up the values from the
wrong style data.

So this large patch essentially does nothing but replace the
context argument in all compute functions with new arguments for the 3
cases above:
(1) values
(2) parent_values
(3) provider

We apparently have a lot of computing code.

4a281edc87 stylecontext: Only create transitions conditionally
While regular animations should always be created, transitions should
not. This patch allows to express this by passing NULL as the values to
transition from.

It also adds a gtk_style_context_should_create_transitions() function
that returns TRUE when transitions should be created.

229b6fe17a css: Add animation support
This adds the GtkCssAnimation class and the code needed to hook it into
GtkStyleContext. It takes the values out of the CSS "animation"
properties and does animations. See
  http://dev.w3.org/csswg/css3-animations/
for details.

Note that the code for starting and stopping animations with widget
visibility doesn't work yet.

60eff87d08 stylecontext: Shuffle around code
This has two goals:

1) Move invalidation code out of a nested if branch. Invalidation is
actually the most important thing this function does.

2) Have the changes bitmask available. It will needed for invalidate
calls to children later.
