 //! This crate provides a Bevy plugin, [`OutlinePlugin`], and associated components for
 //! rendering outlines around meshes using the vertex extrusion method.
-//! 
+//!
 //! Outlines are rendered in a seperate pass following the main 3D pass. The effect of this
 //! pass is to present the outlines in depth sorted order according to the model translation
 //! of each mesh. This ensures that outlines are not clipped by other geometry.
-//! 
+//!
 //! The [`Outline`] component will, by itself, cover the original object entirely with the
 //! outline colour. The [`OutlineStencil`] component must also be added to prevent the body of
 //! an object from being filled it. This must be added to any entity which needs to appear on
 //! top of an outline.
-//! 
+//!
 //! Vertex extrusion works best with meshes that have smooth surfaces. For meshes with hard
 //! edges, see the [`OutlineMeshExt::generate_outline_normals`] function.
