That warning only applies to the "Display Routines and Structures section,
from page 335 to 353.  The off-limits routines are LoadView(), MrgCop()
and MakeVPort().  Use the Intuition equivalents RethinkDisplay(),
RemakeDisplay() and MakeScreen() instead.  The double-buffering
techniques described on page 355 doesn't work with intuition, and the
dual-playfield stuff requires some care (although it can be done).
Onther than that, anything goes, particularly pages 357 onwards.
(Although Intuition prepares a RastPort for you when it gives you
a window; there's no need to allocate one of your own.)

Graphics Primitive:		Intuition equivalent:
View				Off-limits
ViewPort			Screen
RastPort			Window
