Rotation
------------------------------------------------------------------------------
The device rotation applies a corrective angle to relative input events.
This is currently only available on trackpoints which may be used sideways
or upside-down. The angle can be freely chosen but not all devices support
rotation other than 0, 90, 180, or 270 degrees. Rotation is off (0 degrees)
by default.
The device rotation applies a corrective angle to relative input events,
allowing the device to be used e.g. sideways or upside-down. For example, a
trackball may be used in a 90° rotated position for accessibility reasons -
such a rotated position allows triggering the buttons with the thumb or
the non-dominant hand.
