About

This component exists so that you can influence aspects of your Canvas renders using CSS, where style decisions belong. For details view this blog post.

Performance

Generating and computing styles for ~2000 unique selectors in chrome takes ~300ms, so be careful if you plan on using this for many unique selectors. Values are otherwise cached in an object and can easily operate above 300,000 ops/s.
