title: C++: When should I use structs instead of classes and where are the speed differences?
body: <ul>
  <li><p>When should I use a <code>struct</code> instead of a class? I'm currently using classes for everything from OpenGL texture wrappers to bitmap fonts.</p></li>
  <li><p>Is a class that I use just like a <code>struct</code> (no making usage of inheritance, polymorphism, etc.) still slower than a <code>struct</code>?</p></li>
  </ul>
