[gtk+/wip/baedert/drawing: 209/262] icon: Render at content position



commit 6b5fdee55786156af1d29c1b1dff80d2823cf6c0

    icon: Render at content position
    
    Since we get offset automatically to the widget allocation before
    ->snapshot is called, we still have to offset the difference to the
    position of the content allocation.
