Screen does not update about js-vnc-demo-project

Thanks for the issue! Next a couple of days I'm going to debug it and see how it could be fixed.

The installation of node-png is a little bit tricky. In order to make it run you need libpng and I think you cannot compile it with the latest node, so you will need not newer version than ~0.10.13.

After making node-png running, everything should work properly.

I had all dependencies installed and the screen loads successfully upon login. It just doesn't "update".
I tried putting r.requestUpdate(...) into the r.on('rect') handler but even that is still very sluggish.
Note: the VNC server I test this with is running TightVNC server version 1.2.9

I'm going to keep the issue open, hopefully I'll be able to reproduce it.

The screen doesn't update, same here.

Can't find anywhere emitting .emit('rect',rect), maybe that's the problem?

Today I found time and reproduced the issue.

I tried to connect to TightVNC server but it didn't work. I guess there was a problem in the frame encoding or may be security?

With RealVNC it works properly. I also added polling for changes, the polling is not incremental i.e. every time the proxy requests the whole screen. In order to make it incremental change the flag passed to requestUpdate.

I'm trying it on RealVNC but the issue is produced

@RonCan did you pull the last changes?
