 Fixed image rendering will automatically append a variable `q` parameter mapped to each `dpr` parameter when generating a `srcset`. This technique is commonly used to compensate for the increased filesize of high-DPR images. Since high-DPR images are displayed at a higher pixel density on devices, image quality can be lowered to reduce overall filesize without sacrificing perceived visual quality. For more information and examples of this technique in action, see [this blog post](https://blog.imgix.com/2016/03/30/dpr-quality?_ga=utm_medium=referral&utm_source=sdk&utm_campaign=rails-readme). This behavior will respect any overriding `q` value passed in via `url_params` and can be disabled altogether with `srcset_options: { disable_variable_quality: true }`.
