public int mouse_mode { get; }

Spice protocol specifies two mouse modes, client mode and server mode.

In client mode (spice_mouse_mode_client), the affective mouse is the client side mouse: the client sends mouse position within the display and the server sends mouse shape messages. In server mode (spice_mouse_mode_server ), the client sends relative mouse movements and the server sends position and shape commands.
