Tree Node Animation in SwingSet2(GTK) is unlike the native Mercury Tree Node animation.

Steps to Reproduce:
-------------------
1) Run SwingSet2 with the Swing PIT of 25th July with -Dswing.gtkthemefile=<Your gtkrc file > and change the LAF to GTK.
2)Click the tree demo.
3)Click the node.
4) Notice the the node image animation.
5) Now Open any native application with tree.
6) Click any node and see the node animation . It is different from the Java gtk
tree node animation.

Note: The Linux flavour is SUSE 8 and Mercury build is 03
