   Changes:
   * Build fixes.
   * Misc. documentation fixes.
   * Misc. buffer overflow and memleak fixes.
   * Support for OpenSSL 1.1.0.
   * Fix for Debian bug #672435.
   * Added support for the X Composite Extension. For subwindow/appshare
     modes this allows sharing the respective window/app when it
     is partially or completely off-screen as XComposite renders
     the window contents to an off-screen buffer. Before, updating
     of the window contents would stop once it went even partially
     off-screen.
   * Added XInput 2 multi-pointer support which allows multiple clients
     to view and control a single shared screen, all having their
     own mouse pointers and keyboard foci. For in-depth info, read
     http://edoc.hu-berlin.de/master/beier-christian-2011-07-19/PDF/beier.pdf,
     especially section 5.1.
  
     Added some support for running under Wayland via the deskshot utility
     found in the misc/ subdirectory.
