[Qemu-devel] [PATCH v4 10/10] spice: add tablet support |

Add support for the spice tablet interface. The tablet interface will
be registered (and then used by the spice client) as soon as a absolute
pointing device is available and used by the guest, i.e. you'll have to
configure your guest with '-usbdevice tablet'.
