It has to be a valid drawable, yes. You're right, they don't say that 
explicitly in the documentation. But this is why everyone waits until 
the first call to drawRect: to set the context's view. I find that odd 
and a bit clumsy, but my attempts to find another more reasonable point 
at which to set it up all involve a delay which leaves the view 
unpainted for a brief moment.

The exception to this is if one subclasses NSOpenGLView, which sets the 
context in its implementation of LockFocus. I had to create a subclass 
of NSOpenGLContext to figure that out.
