We have decided to remove Ruler service, and so it is not part of the public API.

@mhevery is there any alternative already available for the Ruler service?

For now just use the DOM directly. This will only be an issue if you run your app in WebWorker

See also #8509 (comment) I haven't found any info yet how to create and provide a custom renderer for different platforms (server, webworker, browser DOM thread)
