0ae7c30105 Add & use GTK_CSS_AFFECTS_TRANSFORM
This avoids invalidating the size of all widgets when updating CSS
transforms.

In theory, we don't even have to allocate the widget itself, because we
didn't change its size. But we have no way to track that.

0afdd84a2a css: Clipping changes don't need a queue_allocate() anymore
Now that queue_draw() isn't restricted to clip anymore, we don't need to
care about clip in the CSS engine either.

We do keep GTK_CSS_AFFECTS_CLIP around though because GtkWindow does
care for the window's size.

83fb7a649f css: Merge GtkStyleProviderPrivate into GtkStyleProvider
This is just lots of renaming.

The interface remains private, so the public API does not change, apart
from removing the definition of the Interface object to avoid
subclassing.

4e24cb8588 css: Add GTK_CSS_AFFECTS_ICON_SIZE
And use it in GtkIconHelper. This way, we can avoid resizes when e.g.
the fg color of a symbolic icon changes.

9bc7581f1c css: Replace _AFFECTS_TEXT with _TEXT_SIZE and _TEXT_CLIP
It was used to mark css properties that affect widgets with text, but it
caused unnecessary invalidations. E.g. 'color' was marked as
AFFECTS_TEXT but changing just the color of a label should not
automatically queue a resize, which is what the code in
gtk_widget_real_style_updated does.

Replace this flag with GTK_CSS_AFFECTS_TEXT_SIZE and
GTK_CSS_AFFECTS_TEXT_CLIP, which GtkWidget can use only if the widget
actually has text.

6859f0a6d1 css: Use enums instead of idents for font-variant properties
As Benjamin says, ident should only be used if any value
is valid, which is not the case here. So use enums instead,
which should also be more efficient. To handle the more
complicated cases like font-variant-ligatures, we have to
introduce flags-like values.

92398bb1bb css: implement font-variant as a shorthand
Drop the current css2-style font-variant property and
replace it with a shorthand as specified in the css3 fonts
module. Currently, we fully support the font-variant-ligatures,
font-variant-position, font-variant-caps, font-variant-numeric
and font-variant-east-asian subproperties. font-variant-alternatives
is only partially supported.

aa917ce3b7 css: Redo GtkCssAffects
We now have GTK_CSS_AFFECTS_CONTENT for properties that have an effect
on content rendering.

Using GTK_CSS_AFFECTS_ICON is wrong for icon-transform and icon-filter
as they don't change the icon, just how the icon is rendered, so we use
GTK_CSS_AFFECTS_CONTENT for those.

We also introduce GTK_CSS_AFFECTS_POSTEFFECT for opacity and filter -
properties that affect the whole drawing of the widget by applying an
effect after everything is said and done.

071c9a8221 API: gdk: Add gdk_rgba_is_clear() and gdk_rgba_is_opaque()
I want to use these inside GSK, and I'm not a fan of putting GdkRGBA
APIs into it or duplicating it into GTK.

So public API it is.

369db4a406 css: add background-blend-mode support
CSS supports blend modes, in which a series of layers are
merged together according to the given operation or set of
operations.

Support for blend modes landed on Cairo, which exposes all
the commons and also the exquisites blend modes available.
Adding support for blend modes, then, is just a matter of
using the available Cairo operations.

This patch adds the background-blend-mode CSS enum property,
and adapts the background rendering code to blend the backgrounds
using the available blend modes when they're set.

e2d966eda5 cssnumbervalue: Remove gtk_css_number_value_get_unit()
This is in preparation for calc(), as calc(50% - 5px) is valid CSS
but has 2 units. Instead, add a function to query a value's dimension
(so we can differentiate lengths from numbers) and add a function to
query if the value contains percentages.

fdba244c38 Add the caret-color CSS property
This property is defined in http://www.w3.org/TR/css3-ui/#caret-color.
We also add a -gtk-secondary-caret-color property, since GTK+ has
supported differently colored split cursors in the past. Unlike
CSS, we don't support the weakly defined auto keyword, and just
use currentColor as the initial value.

7fa37e4bf8 css: Introduct -gtk-icon-palette
This borrows heavily from the CSS4 fonts draft's font-palette, currently
found at https://drafts.csswg.org/css-fonts-4/#font-palette-control

The palette is mainly meant to trigger invalidations when colors used for
symbolic icons change, to potentially allow extending supported colors
in symbolic icons and to recolor all colors of a symbolic icon, not just
the main one.

The syntax for the property goes like this:
Name:        -gtk-icon-palette
Value:       default | name <color> [ , name <color> ]*
Initial:     default
Applies to:  all elements with icons
Inherited:   yes
Animatable:  yes, each color animated separately

The property defines a list of named colors to be used when looking up
icons. If a name is not defined, the value of the current "color"
property is used. Which names are relevant depends on the icons in use.
Currently symbolic icons make use of the names "success", "warning" and
"error".

"default" is the current behavior of the GTK when coloring symbolic
icons and is equal to the string
  success @success_color, warning @warning_color, error @error_color

Animation is crudely implemented by animating colors that are in both
palettes that are animated and otherwise keeping the color from the
palette that defined it. Note that this can cause a sharp cut at the
beginning or end of the animation when the color goes away and will
therefore be replaced with the color property.

f0a1a0c0a4 gtk/gtkcsstypesprivate.h: Fix Build
The recent change to the enum declaration for GtkCssChange actually
relied on compiler-dependent behavior, which also breaks the build on
some non-GCC compilers, such as Visual Studio.  As noted in the
G_STATIC_ASSERT line just beneath this declaration, we need to change
this enum declaration to #define's, in order to fix the build in such
situations.
