Cómo deshabilitar o modificar el relleno de TreeCell en TreeView

Question

Entorno: JDK 7u75, Windows 8.1 x64, JavaFX2.2

Código de muestra:

public class TreeViewSample extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) throws MalformedURLException {
primaryStage.setTitle("Tree View Sample");
TreeItem<String> rootItem = new TreeItem<String>("RootNode");
for (int i = 1; i < 5; i++) {
TreeItem<String> item = new TreeItem<String>("SubNode" + i);
rootItem.getChildren().add(item);
item.getChildren().add(new TreeItem<String>("SubSubNode" + i + "" + i));
}
rootItem.getChildren().add(new TreeItem<String>("SecondRootNode"));
TreeView<String> tree = new TreeView<String>(rootItem);
StackPane root = new StackPane();
root.getChildren().add(tree);
Scene scene = new Scene(root, 300, 250);
scene.getStylesheets().add((new File("../css/styletest.css").toURI()).toURL().toString());
primaryStage.setScene(scene);
primaryStage.show();
}
}

CSS:

.tree-cell {
-fx-skin: "com.sun.javafx.scene.control.skin.TreeCellSkin";
-fx-background-color: -fx-control-inner-background;
-fx-padding: 0.25em; /* 3 */
-fx-text-fill: -fx-text-inner-color;
-fx-indent: 10;
}
.tree-cell .label {
-fx-padding: 0.0em 0.0em 0.0em 0.25em; /* 0 0 0 3 */
}
.tree-cell .tree-disclosure-node {
-fx-padding: 4 2 4 8;
-fx-background-color: transparent;
}
.tree-cell .tree-disclosure-node .arrow {
-fx-background-color: -fx-mark-color;
-fx-padding: 0.333333em; /* 4 */
-fx-shape: "M 0 -4 L 8 0 L 0 4 z";
}

Necesitamos eliminar todo el espacio y las flechas para todos los nodos. CSS modificado:

.tree-cell {
-fx-skin: "com.sun.javafx.scene.control.skin.TreeCellSkin";
-fx-background-color: -fx-control-inner-background;
-fx-padding: 0px;
-fx-text-fill: -fx-text-inner-color;
-fx-indent: 0px;
}
.tree-cell .label {
-fx-padding: 0.0em 0.0em 0.0em 0.0em;
}
.tree-cell .tree-disclosure-node {
-fx-padding: 0px;
-fx-background-color: transparent;
}
.tree-cell .tree-disclosure-node .arrow {
-fx-background-color: -fx-mark-color;
-fx-padding: 0.0em;
}

Como ve, no hay relleno y sangría para todos los nodos excepto hojas.

Y la pregunta: ¿cómo eliminar / modificar este relleno?
