22 Specifies the source of a control. This provides a way for setting sources for
23 different types of controls in a uniform way.

37 Provides further abstraction on top of input devices. There are two types of
38 controls currently defined: BinaryControl and SmoothControl.
40 A control uses either a button or half of an axis (positive or negative) as its
41 source. How the source values are interpreted depends on the exact type of the
42 control. Controls also support interactive binding by capturing a button press
