    Add new event path & Change pixmap 24 to 32.

    Fix the bug of size_changed event.
    It has to send the fbid to the client to update its buffer info from viewer side.

    Separating slaves(using net option), 0x0 size box

    1. Separate the slave process using network option.
       If a box requires network connection to update their contents,
       Load it from specific slave which designed to use the network.

       Currently, we use only one package for loading boxes.
       So we just launch another slave process for separating boxes using network attributes.

    2. 0x0 box size is added.
       0x0 is supported for inhouse/commercialization version only.
       Its size is defined 720x1280 (depends on the screen size)

    Add new event path for holding scroller of viewer

    Viewer should holds the scroller when it gets this event.
    This hold scroll event is used for get request of boxes.
