* A shadow list can be applied to text or symbolic icons, using the CSS3

* A text shadow is specified using the syntax
* <literallayout>text-shadow: @horizontal_offset @vertical_offset [ @blur_radius ] @color</literallayout>
* The offset of the shadow is specified with the @horizontal_offset and @vertical_offset
* parameters. The optional blur radius is parsed, but it is currently not rendered by
* the GTK+ theming engine.
* </para>
* <para>
* To set multiple shadows on an element, you can specify a comma-separated list
* of shadow elements in the text-shadow property. Shadows are always rendered
* front-back, i.e. the first shadow specified is on top of the others. Shadows
* can thus overlay each other, but they can never overlay the text itself,
* which is always rendered on top of the shadow layer.
