* @GTK_CSS_AFFECTS_PANGO_LAYOUT: Font rendering is affected.

* @GTK_CSS_AFFECTS_TEXT: Text rendering is affected.
* @GTK_CSS_AFFECTS_TEXT_ATTRS: Text attributes are affected.
* @GTK_CSS_AFFECTS_ICON: Fullcolor icons and their rendering is affected.
* @GTK_CSS_AFFECTS_SYMBOLIC_ICON: Symbolic icons and their rendering is affected.
* @GTK_CSS_AFFECTS_OUTLINE: The outline styling is affected. Outlines
* only affect elements that can be focused.
* @GTK_CSS_AFFECTS_CLIP: Changes in this property may have an effect
* on the clipping area of the element. Changes in these properties
* should cause a reevaluation of the element's clip area.
* @GTK_CSS_AFFECTS_SIZE: Changes in this property may have an effect
* on the allocated size of the element. Changes in these properties
* should cause a recomputation of the element's allocated size.
*
* The generic effects that a CSS property can have. If a value is
* set, then the property will have an influence on that feature.
*
* Note that multiple values can be set.
