I assume you have to do something to set up the view appropriately?
How is that done?

Bill,
The best intro to OpenGL for most beginners is nehe.gamedev.net, but
use the Cocoa examples available at www.withay.com. There is a starter
project which just opens an OpenGL view, and a follow-up which draws a
triangle. The basics of OpenGL are really simple and easy to pick up,
and for 2D the rest is just a bunch of drawing commands and state set
calls. The trick is that your drawing commands aren't retained between
screen redraws -- you have to do that yourself in your view or your own
drawing classes.
The Red Book (OpenGL Programming Guide) is available online
