Implementing client to use resizing-method display-update

[Bbiswabasu Roy]

I have set the property "resize-method" to "display-update" on the Java
server and on the client side, I am calling client.sendSize(x,y) whenever
the window resizes. Using the tunnel.oninstruction() event, I also found
that instruction with opcode "size" are being received on the client side.
But the remote display size on the client is not updating. What am I
missing?
