 The 'clip-rule' property indicates the algorithm which is to be used to determine whether a given point is inside a shape for a <i>clipping region</i> created with a <a>graphics element</a>. The definition of the algorithms and the 'clip-rule' values follows the definition of the 'fill-rule' property.
