X region 'damage' library
 libXdamage provides the client-side interface to the DAMAGE extension,
 which allows for notification of changes to regions.
 .
 This requires server-side support, which was introduced in X.Org's X11R6.8,
 and is also present in most versions of freedesktop.org's 'KDrive' server
 (also known as 'xserver', or 'freedesktop.org X server').
