Up, Coordinates, and Gravity

Several comments on coordinate systems and the issue of which way is "up"
have appeared here recently. Rather than globaly define +y or +z as up,
how about defining a characteristic of a spacial volume that is a gravity
vector.

Gravity { 0.0, -9.8, 0.0 }

For instance, in an area where +y is "up". Viewers could then (optionally)
orient the view according to the prevailing gravitational field.
