     NAME
          XPolygonRegion, XClipBox - generate regions

     SYNOPSIS
          Region XPolygonRegion(points, n, fill_rule)
                XPoint points[];
                int n;
                int fill_rule;

          XClipBox(r, rect_return)
                Region r;
                XRectangle *rect_return;

     ARGUMENTS
          fill_rule Specifies the fill-rule you want to set for
                    the specified GC.  You can pass 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.

     DESCRIPTION
          The XPolygonRegion function returns a region for the
          polygon defined by the points array.  For an
          explanation of fill_rule, see XCreateGC.

          The XClipBox function returns the smallest rectangle
          enclosing the specified region.
