static float EaseIn	(	float	time,
		float	startValue,
		float	changeValue,
		float	duration,
		float	unusedOvershootOrAmplitude,
		float	unusedPeriod
	)		[static]

Easing equation function for a quadratic (t^2) easing in: accelerating from zero velocity.

Parameters:

time	Current time (in frames or seconds).
startValue	Starting value.
changeValue	Change needed in value.
duration	Expected easing duration (in frames or seconds).
unusedOvershootOrAmplitude	Unused: here to keep same delegate for all ease types.
unusedPeriod	Unused: here to keep same delegate for all ease types.

Returns:

The eased value.
