useWhen: input near zero is ignored on purpose

Physical inputs do not rest at zero. A thumbstick that has been leaned on for two years reports
a small permanent offset, a trackpad reads a fingertip's tremor, a tilt sensor picks up the
train. If the interface believes all of it, the camera drifts while nobody is touching
anything, and the reader learns that the device is broken. A dead zone is the fix, and it is
deliberately crude: a range around the neutral position where the input is thrown away and the
output is exactly zero. Control engineering has called this a deadband for far longer than
games have, and the same idea keeps a thermostat from switching on and off every few seconds.

The pattern is not only about sticks. A pan control that sits silently at centre until you
move meaningfully off it, a rotation handle that refuses to report a fraction of a degree, a
scrubber that will not scrub until you mean it, a colour picker that snaps to true neutral
near the middle of the wheel: all of them are the same trade, spending a little precision near
the rest position to buy silence there. The cost is real. Everything inside the band is
unreachable, so a control with a wide dead zone can no longer express a small value at all,
and the reader feels it as a stick that suddenly lurches.

Which is why the good implementations rescale rather than clip. Clipping means the first
sample past the band jumps straight to the value it always had, so the output leaps from zero
to eighteen percent in one pixel. Rescaling remaps what is left of the range onto the whole
output, so the edge of the band emits nearly nothing and the full deflection still emits
everything. It costs one line of arithmetic and it is the difference between a control that
feels sticky and one that feels calm. The size should be adjustable, too, because the band a
worn controller needs is not the band a new one needs.

Two neighbouring terms are easy to confuse with it. A drag threshold is a distance the pointer
must travel before a gesture is allowed to begin, and it is spent once per gesture. A dead
zone is a region where input is ignored for as long as the input stays inside it, gesture or
no gesture. Hit slop is the opposite move on the same axis: slop grows the region that answers
so a near miss counts, while a dead zone shrinks the region that answers so a near miss does
not.
