Pure derivation of a parallax plane's inner View from the camera view
plus per-plane factors.
pan controls how much the plane translates with the camera (1 = normal,
0 = locked to anchor, >1 = leads). zoom controls how much it scales
with camera zoom (1 = normal, 0 = fixed at identity scale). anchor
(default origin) is the world point all planes agree on.
Identity holds: pan=1, zoom=1 returns a view equal to outer.
