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 contained
     in the region r.

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