We want to just use the current icon theme, always.

67991ed0f4 Remove GtkCssRgbaValue
The differenciation between a literal color value and an RGBA value
caused problems in various situations. Just treat the two the same but
don't allow access to the rgba value of a non-literal color value.

This gets rid of around 1.6k rgba values in the widget-factory.

4f3e65e745 csspalettevalue: Use simple arrays instead of a hashtable
Use two sorted name/value arrays to save the colors instead of a
hashtable. This makes palette values faster to compare etc.

3322599e99 css: Introduce the idea of dynamic values
Dynamic values are values that change their contents with the current
(monotonic) time.

This just introduces the GtkCssValue API for it.

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.

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.
