Region XPolygonRegion(XPoint points[], int n, int
fill_rule);
int XClipBox(Region r, XRectangle

EvenOddRule or WindingRule.
- n
- Specifies the number of points in the polygon.
- points
- Specifies an array of points.
- r
- Specifies the region.
- rect_return
- Returns the smallest enclosing rectangle.
