commit 867bee66a727b60b66f29c98e29c76b796e66a63
Author: Jonathon Jongsma <jjongsma at redhat.com>

    Add CursorChannelPrivate struct
    
    Encapsulate private data of CursorChannel in a private struct. This
    isn't very useful at the moment, but it will help prepare the way for
    porting the RedChannel heirarchy to GObject.
