Since the introduction of mapped sector planes the "visual height" of a plane could be interpreted with two very different meanings depending on the context.
Sector cluster allows mapping of planes for visual effect only and so the term "visual" is now overloaded (previously this identified the interpolated "smooth" height of a plane).
To disambiguate, Plane's API now uses the term "smoothed" and for uniformity, Surface applies the same terminology when identifying the smoothed material origin.

Refactor|World|Plane|Surface: Disambiguate "visual height" wrt planes
