 * @GTK_CSS_AFFECTS_BORDER: The border styling is affected.
 * @GTK_CSS_AFFECTS_PANGO_LAYOUT: Font rendering is affected.
 * @GTK_CSS_AFFECTS_FONT: The font is affected and should be reloaded
 *   if it was cached.
 * @GTK_CSS_AFFECTS_TEXT: Text rendering is affected.
 * @GTK_CSS_AFFECTS_ICON: Icons and icon 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.
