<div class="markdown level1 summary"><p>Adds a new optimization point, with target bitrate 'brate' and with
'elyrs' (unoptimized) extra layers after it. The target bitrate 'brate'
must be larger than the previous optimization point. The arguments are
checked and IllegalArgumentException is thrown if they are not correct.</p>
