Before this CL, the current rcp (1/x) calculation has enough precision
for color calculations, but not enough for positional calculations.
Introduce a new reciprocal called recip that has more precision for
positions. On Intel, this requires the addition of a Newton-Raphson
iterations, and ARM requires two NR iterations.

Per spec, reading anything other than the most recently written
union member is undefined behavior.
Keyframe containers always access the same member, consistently. But
the type-agnostic equality operator does touch both members.
Refactor to avoid undefined behavior.
Also add a couple of unit tests to capture keyframe deduping behavior
(which in turn relies on the equality operator).
