Comment 6 for bug 224248

I'm sorry I'm still not following. I'm not seeing how the protocol has anything to do with this. This is a client side issue as far as I can see. The client knows (at some point) how big the remote screen is that it's displaying. It would also have some idea how big the local display is. It shouldn't be a major undertaking for the client to increase its vertical window size to eliminate an unnecessary scroll bar.
