    revealer: Request child size for NONE transition type
    
    Previously, we would request a size of 0×0 when the transition type was
    NONE and the child un-revealed, making the revealer in this case a
    gtk_widget_set_visible replacement. Instead, to the exact same thing we
    do in the CROSSFADE case and request the child size instead. This also
    keeps the revealer from under allocating the child when the transition
    type is set to NONE.
