/*!
* \ingroup joystick
* \brief Basic driver element associated with input events
*
* Driver input (bools, floats and enums) is split into primitives that better
* map to the physical features on a joystick.
*
* A bool obviously only maps to a single feature, so it is a driver
* primitive. Here, these are called "buttons".
*
* A hat enum encodes the state of the four hat directions. Each direction
* can map to a different feature, so a hat enum consists of four driver
* primitives called "hat directions".
*
* A float is a little trickier. Trivially, it can map to an analog stick or
* trigger. However, DirectInput combines two triggers onto a single axis.
* Therefore, the axis is split into two primitives called "semiaxes".
*
* The type determines the fields in use:
*
* Button:
* - driver index
*
* Hat direction:
* - driver index
* - hat direction (up/right/down/left)
*
* Semiaxis:
* - driver index
* - center (-1, 0 or 1)
* - semiaxis direction (positive/negative)
* - range (1 or 2)
*
* Motor:
* - driver index
*
* Key:
* - keycode
*
* Mouse button:
* - driver index
*
* Relative pointer:
* - pointer direction
*
* For more info, see "Chapter 2. Joystick drivers" in the documentation
* thread: http://forum.kodi.tv/showthread.php?tid=257764
