VncThread - communicate with VNC server, scale image if necessary.
As this class is derived from QThread and overrides the run() method, it does not have an event-loop. Do NOT try to add any slots to it. It will NOT be able to receive signals. Emitting signals is fine though.

Initialize this VNC client connection worker thread.
- Parameters
-
| host | The IP address of the VNC server we're going to connect to |
| port | The port of the VNC server |
| passwd | The password of the VNC server |
| quality | The desired quality level for the VNC stream |

- Returns
- A strdup()ed copy of the password we'll try to connect with. The memory if free()d by the vnc client library.

Handle update of an area of the VNC framebuffer.
Will do any scaling if necessary and then emit the imageUpdated signal, so the VncWindow knows that it needs to redraw.
- Parameters
-
| x | X offset of the area in the framebuffer that changed |
| y | Y offset of the area in the framebuffer that changed |
| w | width of the area in the framebuffer that changed |
| h | height of the area in the framebuffer that changed |

Worker thread's mainloop, connecting to the VNC server and handling the connection.
The vnc client library is written in a blocking manner, so we just do everything in our own thread and just hand over the image updates to the vnc client window, which resides in the application's main thread.
This thread checks if the vnc window signaled us to stop and if so, it deletes itself. This means that you should never delete this thread from anywhere. Just call VncThread::stop() and wait for it to delete itself.

Callback for the vnc client lib: A part of the frame buffer has changed.
That means we have to apply scaling if necessary, and then cause the vnc window to redraw the corresponding area.
- Parameters
-
| client | Struct representing the connection to the server. |
| x | X offset of the area in the framebuffer that changed |
| y | Y offset of the area in the framebuffer that changed |
| w | width of the area in the framebuffer that changed |
| h | height of the area in the framebuffer that changed |
