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

SYNTAX
       Bool XEmptyRegion(Region	r);

       Bool XEqualRegion(Region	r1, Region r2);

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

       int XRectInRegion(Region	r, int x, int y, unsigned int width, unsigned
	      int 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 con-
       tained in the region r.

       The XRectInRegion function returns RectangleIn if the rectangle is en-
       tirely in the specified region, RectangleOut if the rectangle is	en-
       tirely out of the specified region, and RectanglePart if	the rectangle
       is partially in the specified region.
