function apparentWidth
cinematic.ts:734
apparentWidth(length: number, range: number, fovDeg: number, aspect: number) → number
Apparent size of an object, as a fraction of the frame's width.
The inverse of the measurement a bounding box gives: an object length
across at range covers this much of the frame. Used to state a beat's
range in the units the reference was measured in, and asserted by tests.
