In depth
Clamped rather than extrapolated. A weight past the ends puts limbs outside their range,
which reads as a broken rig rather than as a weight out of bounds — the same reasoning
sampleClip holds at a track's ends for. What it costs is that a caller cannot deliberately
overshoot; what would make it wrong is somebody wanting to, and the honest answer then is a
function that says so in its name.
Safe when out is also a or b: every component is read before it is written.
