    Bug 705397 - Layer groups are not exported properly/fully
    
    In gimpgrouplayer.c always gimp_pickable_flush() after
    gimp_projectable_structure_changed() so all queued updates are
    actually flushed to the projection buffer's invalid area, and are
    constructed upon reading. This would have been neccessary before for
    group layers, but worked anyway until we changed
    gimp_projection_get_buffer() to construct the buffer on idle time
    initially in order to make images appear more responsively after
    loading.
