             teach you about textures is that they are not <emphasis>that</emphasis> important. What
             you have learned is how to think about solving graphics problems without
             textures.</para>
-        <para>Many graphics texts overemphasize the importance of textures; most of them introduce
-            textures before even talking about lighting. This is mostly a legacy of the past. In the
-            older days, before the availability real programmable hardware, you needed textures to
-            do anything of real importance in graphics rendering. Textures were used to simulate
-            lighting and various other effects. If you wanted to do anything like per-fragment
-            lighting, you had to use textures to do it.</para>

         <para>Yes, textures are important for creating details in rendered images. They are
             important for being able to vary material parameters over a polygonal surface. And they
             have value in other areas as well. But there is so much more to rendering than textures,
