weston/0001-simple-touch-Add-maximized-fullscreen: Add maximized/fullscreen for simple-touch

simple-touch wasn't able to resize itself to max/fullscreen to this
patch adds support for that. It is quite useful to have this client
test out touch support, so we can re-use it whenever, for instance in
the virtio aarch64 machine to test if we have indeed or not a
touchscreen device.
