  OK, I've said it.  WHAT is a CALayer?  I'm using a lot of them and
appreciate what they can do, but still don't understand them.

It's an object that manages an OpenGL surface, its location in 3D space and its place in a hierarchy of layers.


Does that help?

I don't know about Gordon, but it helps *me*. I only have a rough idea about CALayer from one ADC video I half-watched, and didn't know until looking at the class doc just now that it's a model class. For some reason I'd thought it was a view class.
