        * javax/swing/plaf/metal/MetalTreeUI.java
        (installUI): Fixed to call toggleExpandState instead.
        * javax/swing/plaf/basic/BasicTreeUI.java
        (getPathForRow): Used currentVisiblePath to get Path.
        (getRowForPath): Used currentVisiblePath to get row.
        (getRowCount): Returned currentVisiblePath length.
        (updateLayoutCacheExpandedNodes): Took out unneeded code.
        (installUI): Fixed to call toggleExpandState instead.
        (getPreferredSize): Made more efficent by using 
        currentVisiblePath.
        (toggleExpandState): Called updateCurrentVisiblePath.
        (getCellLocation): Made more efficent.
        (paintNode): Removed.
        (paintRecursive): Made more efficent, changed paintNode calls to
        paintRow.

        (getPreviousVisibleNode): Likewise.
        (paintRow): Implemented.
