+ * \subsection anisotoverview Overview
+ * The RpAnisot plugin is used to extend an RwTexture with a maximum
+ * anisotropy value that will be used when a particular texture is drawn.
+ * When textured polygons are viewed nearly edge on, for example when looking
+ * dowm a road or a football pitch, distant pixels are not sampled very well
+ * by trilinear mipmapping and the texture looks smeary.
+ * Anisotropic sampling takes additional samples, resulting in sharper looking
+ * textures.  Higher numbers of samples will produce better quality results but
+ * run slower, so should be used in moderation.
