NAME
       XEmptyRegion, XEqualRegion, XPointInRegion, XRectInRegion
       - determine if regions are empty or equal

SYNTAX
       Bool XEmptyRegion(r)
	     Region r;

       Bool XEqualRegion(r1, r2)
	     Region r1, r2;

       Bool XPointInRegion(r, x, y)
	     Region r;
	     int x, y;

       int XRectInRegion(r, x, y, width, height)
	     Region r;
	     int x, y;
	     unsigned int width, height;

ARGUMENTS
       r	 Specifies the region.

       r1
       r2	Specify the two regions.

       width
       height	Specify the width and height, which define the
		 rectangle.

       x
       y	 Specify the x and y coordinates, which define
		 the point or the coordinates of the upper-left
		 corner of the rectangle.

DESCRIPTION
       The XEmptyRegion function returns True if the region is
       empty.

       The XEqualRegion function returns True if the two regions
       have the same offset, size, and shape.

       The XPointInRegion function returns True if the point (x,
       y) is contained in the region r.

       The XRectInRegion function returns RectangleIn if the
       rectangle is entirely in the specified region, Rectangle-
       Out if the rectangle is entirely out of the specified
       region, and RectanglePart if the rectangle is partially in
       the specified region.
