rectangles

Chapter 2 says "In SDL rectangles are the most cost effective of the primitives to draw". What does that mean?

Hmm well Rectangles use a special function, which is a lot faster then any of the other primitives. How do I say this?

I don't know that I'd put that in the main part of the text at all. Maybe as a sidebar or something.
