setPointsAttribute(array $points)
Round the floats of the points array to 2 decimals before saving.
This is a more than sufficient precision for annotation point coordinates and saves memory in the DB as well as when processing the annotations in PHP.

array
interpolatePoints(float $time)
Get the interpolated points at a specific point of time.
This method must be equivalent to the interpolatePoints function of the JavaScript annotation model!
