Name
       XCreateRegion, XSetRegion, XDestroyRegion - create or destroy regions

Syntax
       Region XCreateRegion()

       XSetRegion(display, gc, r)
	  Display *display;
	  GC gc;
	  Region r;

       XDestroyRegion(r)
	  Region r;

Arguments
       display	 Specifies the connection to the X server.

       gc	 Specifies the GC.

       r	 Specifies the region.

Description
       The function creates a new empty region.

       The function sets the clip-mask in the GC to the specified region.  Once it is set in the GC, the region can be destroyed.

       The function deallocates the storage associated with a specified region.

Name
       XIntersectRegion, XUnionRegion, XUnionRectWithRegion, XSubtractRegion, XXorRegion, XOffsetRegion, XShrinkRegion - region arthmetic

Syntax
       XIntersectRegion(sra, srb, dr_return)
	  Region sra, srb, dr_return;

       XUnionRegion(sra, srb, dr_return)
	  Region sra, srb, dr_return;

       XUnionRectWithRegion(rectangle, src_region, dest_region_return)
	  XRectangle *rectangle;
	  Region src_region;
	  Region dest_region_return;

	  Region sra, srb, dr_return;

       XXorRegion(sra, srb, dr_return)
	  Region sra, srb, dr_return;

       XOffsetRegion(r, dx, dy)
	  Region r;
	  int dx, dy;

       XShrinkRegion(r, dx, dy)
	  Region r;
	  int dx, dy;

Arguments
       dest_region_return
		 Returns the destination region.

       dr_return Returns the result of the computation.  ds Dy move or shrink

       dx
       dy	 Specify the x and y coordinates, which define the amount you want to  the specified region.

       r	 Specifies the region.

       rectangle Specifies the rectangle.

       sra
       srb	 Specify the two regions with which you want to perform the computation.

       src_region
		 Specifies the source region to be used.

Description
       The function computes the intersection of two regions.

       The function computes the union of two regions.

       The function updates the destination region from a union of the specified rectangle and the specified source region.

       The function subtracts srb from sra and stores the results in dr_return.

       The function calculates the difference between the union and intersection of two regions.

       The function moves the specified region by a specified amount.

       The function reduces the specified region by a specified amount.  Positive values shrink the size of the region, and negative values expand
       the region.
