Set the current fill rule within the cairo context. The fill rule
is used to determine which regions are inside or outside a complex
(potentially self-intersecting) path. The current fill rule affects
both cairo_fill() and cairo_clip(). See cairo_fill_rule_t for details
on the semantics of each available fill rule.
The default fill rule is CAIRO_FILL_RULE_WINDING.
