Sets the logical button mapping for this device, see XSetPointerMapping(3). The string must
be a space-separated list of button mappings in the order of the logical buttons on the
device, starting with button 1. The default mapping is "1 2 3 ... 32". A mapping of 0 deac‐
tivates the button. Multiple buttons can have the same mapping. Invalid mapping strings are
discarded and the default mapping is used for all buttons. Buttons not specified in the
user's mapping use the default mapping. See section BUTTON MAPPING for more details.
