if the driver posts wheels as buttons 4/5 the server will ignore them if it
isn't set up. So the previous snippet is correct though without mouse
wheel support.

To get the wheel support, just inc NBUTTONS to 7 and set it up with the
labels BTN_LABEL_PROP_BTN_WHEEL_UP, BTN_LABEL_PROP_BTN_WHEEL_DOWN,
BTN_LABEL_PROP_BTN_HWHEEL_LEFT, BTN_LABEL_PROP_BTN_HWHEEL_RIGHT.

Note that button labelling is still optional, a label of 0 is permitted.
Labels are a hint to clients so they know what a given button does. For any
button from 1-7 labels are arguably superfluous since we can't change much
anyway - too many clients rely on the current behaviour.
