Functions
template<typename T >
T	asw::easing::detail::mix (const T &a, const T &b, float f)
	a + (b - a) * f. Integer types are worked in floating point, so a falling unsigned range does not wrap, and a result past the range of T, e.g. from an overshooting easing, is clamped to it.
float	asw::easing::linear (float t)
float	asw::easing::smoothstep (float t)
	Soft at both ends, 3t^2 - 2t^3.
float	asw::easing::ease_in_quad (float t)
float	asw::easing::ease_out_quad (float t)
float	asw::easing::ease_in_out_quad (float t)
float	asw::easing::ease_in_cubic (float t)
float	asw::easing::ease_out_cubic (float t)
float	asw::easing::ease_in_out_cubic (float t)
float	asw::easing::ease_in_sine (float t)
float	asw::easing::ease_out_sine (float t)
float	asw::easing::ease_in_out_sine (float t)
float	asw::easing::ease_in_expo (float t)
float	asw::easing::ease_out_expo (float t)
float	asw::easing::ease_in_out_expo (float t)
float	asw::easing::ease_in_elastic (float t)
float	asw::easing::ease_out_elastic (float t)
float	asw::easing::ease_in_bounce (float t)
float	asw::easing::ease_out_bounce (float t)
float	asw::easing::ease_in_back (float t)
float	asw::easing::ease_out_back (float t)
float	asw::easing::falloff (float t, asw::Falloff mode)
template<typename T , typename Func >
T	asw::easing::ease (const T &a, const T &b, float t, Func func)
