The type field specifies the type of the input class.
Currently, the following types are defined:
- XIKeyClass, XIButtonClass, XIValuatorClass
+ XIKeyClass, XIButtonClass, XIValuatorClass, XIScrollClass
In the future, additional types may be added. Clients are
required to ignore unknown input classes.

XIModeAbsolute this axis sends absolute coordinates. If the
mode is XIModeRelative, this device sends relative coordinates.

+ This class describes scrolling capability on a valuator. For
+ each XIScrollClassInfo, an XIValuatorClassInfo with the same
+ number is present on the device.
+ The number field specifies the valuator number on the physical
+ device that this scroll information applies to. See the
+ respective XIValuatorClassInfo for detailed information on this
+ valuator.
+ The scroll_type field specifies the type of scrolling, either
+ XIScrollTypeVertical or XIScrollTypeHorizontal.
+ The increment specifies the value change considered one unit of
+ scrolling down.
+ The flags field specifies flags that apply to this scrolling
+ information:
+ If XIScrollFlagNoEmulation is set, the server will not
+ emulate legacy button events for valuator changes on this
+ valuator.
+ If XIScrollFlagPreferred is set, this axis is the
+ preferred axis for this scroll type and will be used for
+ the emulation of XI_Motion events when the driver submits
+ legacy scroll button events.
XIQueryDevice can generate a BadDevice error.
