Fortunately, you're wrong. The book has never mentioned display lists,
glVertex3f and the like. The book approaches it as this is the new-style
OpenGL, it's all shaders, VBOs etc., we're not going to look at
old-style (which is probably why it took so long for them to rewrite
this edition). The whole book is focused on how to use OpenGL 3.3-4.3,
and doesn't even look at old style OpenGL anymore.

So, with the new style, as I understand it, it's not even possible to
use the old OpenGL 2 pipeline (which is why it's not really mentioned in
the book anymore). For example, you need a basic shader to draw even the
most primitive shape, you can't use glVertex3f() etc. to draw a simple
shape, you would have to use a VBO and shader.
