    \class CxuiZoomSlider
    \brief CxuiZoomSlider is a camera specific slider that is derived from HbSlider

    CxuiZoomslider has been created so that we are able to control and filter user
    mouse press events. All mouse press events that happen in slider rect are
    accepted in this class so that they won't be given any other components.
    This has to be done to prevent the slider to dismiss when accidentally 
    missing e.g.slider thumb touch area (camera view underneath will get the 
    event and hide the slider).
