Settings: notification drawer background (1/2)
    so after keyguard is mostly done let us start notification drawer
    and QS. First one custom background.....either color or picture
    with custom alpha and ability to set a landscape picture seperatly
     if the user want. (lanscape phone only)

    Compared to the 4.3 included version completly recoded and better
    integrated. No idea what I thought 1 year ago on the old implementation
