The framebuffer is 16MB, and the max of 1920x1200 was chosen as a
compromise between a common resolution that would fit in that, the
amount of CPU used in the tile-based motion detection, and the amount of
bandwidth required to transmit full-screen's worth of data at 30 fps.
The original intent was the VNC console would only be used for setup,
and after that a more efficient remote desktop would be set up on the guest.
