 Some of the most well-known uses are:
 
-- Outlines: Stencil allows to mask out the inner mesh that is being outlined to avoid inner outlines.
+- Outlines: Mask out the inner mesh that is being outlined to avoid inner outlines.
 - X-Ray: Display a mesh behind other objects.
 - Portals: Draw geometry that is normally "impossible" (non-Euclidian) by masking objects.
 - Shadows: Draw sharp shadows without relying on shadow maps.
