validatePoints(array $points = [])
Validate the points and frames of this annotation.

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.
