/**
* Options for the Boost module. The Boost module allows certain series types
* to be rendered by WebGL instead of the default SVG. This allows hundreds of
* thousands of data points to be rendered in milliseconds. In addition to the
* WebGL rendering it saves time by skipping processing and inspection of the
* data wherever possible. This introduces some limitations to what features are
* available in boost mode. See [the docs](
* https://www.highcharts.com/docs/advanced-chart-features/boost-module) for
* details.
*
* In addition to the global `boost` option, each series has a
* [boostThreshold](#plotOptions.series.boostThreshold) that defines when the
* boost should kick in.
*
* Requires the `modules/boost.js` module.
