LayeredPane

A container that stacks its content on integer depth layers rather than laying it out, realized as a JLayeredPane.

A child declares the depth it sits on with layer, through LayeredPaneScope; a child declaring none stands on JLayeredPane.DEFAULT_LAYER. Within one layer, the children stack in the order the composition declares them, the first of them on top. A layered pane lays no child out, so each child positions itself with SwingModifier.bounds(...):

LayeredPane {
    Background(modifier = SwingModifier.bounds(0, 0, 400, 300))
    FloatingToolbar(modifier = SwingModifier.layer(JLayeredPane.PALETTE_LAYER).bounds(8, 8, 120, 32))
}

Adding or removing a child in the composition adds or removes it on the pane, and a child moves to the layer it declares on recomposition.
