XOffsetRegion()						       XOffsetRegion()

Name
  XOffsetRegion – change offset of a region.

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

Arguments
  r	 Specifies the region.

  dx	 Specify  the amount to move the specified region relative to the
  dy	 origin of all regions.

Description
  XOffsetRegion() changes the offset of the region the specified  amounts
  in the x and y directions.

  Regions  are	located	 using an offset from a point (the region origin)
  which is common to all regions.  It is up to the application to  inter‐
  pret	the location of the region relative to a drawable.  If the region
  is to be used as a clip_mask by calling  XSetRegion(),  the  upper-left
  corner  of  the  region  relative  to the drawable used in the graphics
  request will be at (xoffset + clip_x_origin, yoffset +  clip_y_origin),
  where	 xoffset and yoffset are the offset of the region and clip_x_ori‐
  gin and clip_y_origin are components of the GC  used	in  the	 graphics
  request.

Structures
  Region is a pointer to an opaque structure type.
