Returns a point within the curve at position [code]offset[/code], where [code]offset[/code] is measured as a distance in 3D units along the curve.
To do that, it finds the two cached points where the [code]offset[/code] lies between, then interpolates the values. This interpolation is cubic if [code]cubic[/code] is set to [code]true[/code], or linear if set to [code]false[/code].
Cubic interpolation tends to follow the curves better, but linear is faster (and often, precise enough).
