lerpUnclamped
Performs unclamped linear interpolation between two 2D vectors, a and b.
This function calculates a point along the infinite line defined by vectors a (as the point when t=0) and b (as the point when t=1). Unlike a standard clamped lerp, the interpolation factor t is not restricted to the [0.0, 1.0] range. This means the function can extrapolate beyond the segment connecting a and b.
The formula used is: result = a + (b - a) * t.
Return
A new Vector2 instance representing the linearly interpolated or extrapolated vector.
Parameters
a
The starting vector (value when t=0).
b
The ending vector (value when t=1).
t
The interpolation factor. This value is used as is, without clamping.
