      css: Introduct -gtk-icon-palette · 7fa37e4b
      Benjamin Otte authored
      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.
