function dropRadius
entryArc.ts:265
The radius the camera is at, progress of the way down.
Logarithmic in height, for the reason the surface arm's scrub and the orbit
arm's ease are: the band from an orbit to eye height is six decades, and a
linear schedule spends 99.9% of the drop above the altitude where terrain
is drawn at all and then arrives in a frame. Eased at both ends so the
release is not a lurch and the landing is not a stop. The height is measured
from two meters under the touchdown radius, so the log has a floor to end
on and the last frame lands exactly at touchdown.
