+Sets the button mapping for this device. The mapping is a space-separated list
+of button mappings that correspond in order to the physical buttons on the
+device (i.e. the first number is the mapping for button 1, etc.). The default
+mapping is "1 2 3 ... 32". A mapping of 0 deactivates the button. Multiple
+buttons can have the same mapping.
+For example, a left-handed mouse with deactivated scroll-wheel would use a
+mapping of "3 2 1 0 0". Invalid mappings are ignored and the default mapping
+is used. Buttons not specified in the user's mapping use the default mapping.
