Namespaces
namespace	anonymous_namespace{input.cpp}

Typedefs
using	anonymous_namespace{input.cpp}::ControllerState
	Data structure for controller state, including button states and axis values.

Functions
float	anonymous_namespace{input.cpp}::rescale_dead_zone (float magnitude, float dead_zone)
	Rescale a value past the dead zone so it starts from zero.
asw::Vec2< float >	anonymous_namespace{input.cpp}::read_stick (const ControllerState &cont, asw::input::ControllerStick stick)
	Read a stick with a radial dead zone.
float	anonymous_namespace{input.cpp}::read_axis (const ControllerState &cont, asw::input::ControllerAxis axis)
	Read one axis with the dead zone applied.
template<typename Pred >
bool	anonymous_namespace{input.cpp}::any_controller (uint32_t index, Pred pred)
	Check a button on one controller, or on any when index is ANY_CONTROLLER.
template<typename Action >
bool	anonymous_namespace{input.cpp}::each_controller (uint32_t index, Action action)
	Run an action on one controller, or on all when index is ANY_CONTROLLER.
uint16_t	anonymous_namespace{input.cpp}::to_motor_intensity (float intensity)
	Convert an intensity between 0 and 1 to SDL's motor range.
bool	anonymous_namespace{input.cpp}::has_capability (const ControllerState &cont, const char *property)
	Read a boolean capability from a controller's properties.
std::string	anonymous_namespace{input.cpp}::pad_identity (SDL_JoystickID id, SDL_Gamepad *pad)
	What tells a pad apart when it is plugged back in: its serial number, or its model when it has none. Two pads of one model with no serial look the same.
bool	anonymous_namespace{input.cpp}::slot_empty (std::size_t index)
std::size_t	anonymous_namespace{input.cpp}::pick_slot (const std::string &identity)
	Pick the slot for a pad that just connected.
SDL_WindowID	anonymous_namespace{input.cpp}::simulated_window_id ()
void	anonymous_namespace{input.cpp}::push_simulated_key (asw::input::Key key, bool down)
void	anonymous_namespace{input.cpp}::push_simulated_mouse_button (asw::input::MouseButton button, bool down)

Variables
std::array< SDL_Cursor *, asw::input::NUM_CURSORS >	anonymous_namespace{input.cpp}::cursors { nullptr }
	Active cursor stores the current active cursor. It is updated by the core.
std::vector< ControllerState >	anonymous_namespace{input.cpp}::controller { }
	Global controller state. A slot stays at its index while its pad is unplugged, and the pad gets it back when plugged in again, so bindings keep reading the same physical pad.
std::vector< std::string >	anonymous_namespace{input.cpp}::slot_owner { }
	The pad each slot last held, by pad_identity(). Kept after the pad is unplugged and after its slot is dropped from the end of controller, so the pad can get its slot back.
float	anonymous_namespace{input.cpp}::default_dead_zone { 0.25F }
	Dead zone given to pads when they connect.
std::unordered_map< SDL_JoystickID, uint32_t >	anonymous_namespace{input.cpp}::controller_id_map { }
	Map of SDL_JoystickID to controller index in the controller vector.
asw::input::KeyState	anonymous_namespace{input.cpp}::keyboard { }
asw::input::MouseState	anonymous_namespace{input.cpp}::mouse { }
std::string	anonymous_namespace{input.cpp}::text_input
asw::input::InputDevice	anonymous_namespace{input.cpp}::last_device { asw::input::InputDevice::KeyboardMouse }
