 We also support mixin syntax via `style: sass_mixin`. If set, it will generate a SASS mixin which you can use in order to mix in these sprites anywhere within your SASS stylesheets. For this option, set `style_output_path:` to `stylesheets/sass/_sprites` in order to generate the sass mixin file at `stylesheets/sass/_sprites.sass`
