What is this about?

• Minification happens not only when texture coordinates are so that the texture is minified on the surface it is displayed.
• It can also happen under perspective view when we view a surface at a grazing angle.
• The mipmap is used to anti-alias the minified texture. Each mode of using the mipmap yields different rendering result.
