The View constructor: View(...) makes one (see new_view for its
arguments).
A view of frame (in the tree of root), with base frame_type
(default RELATIVE_FRAME); with lookat, a view from frame at lookat,
turned by rotation_type (default VIEW_AZEL). Without frames, the view
looks at the root frame's origin. The frames must stay alive while the
view is used.
