Detailed Description

Ties one driver to one parameter of one layer.

The parameter is atZero when the driver reads 0 and atFull when it reads 255. atFull below atZero reverses the binding, the same way levelSource()'s fullAt below emptyAt reverses a meter.

curve, when set, points at CURVE_POINTS bytes that reshape the driver's 0-255 before the line is applied, linearly interpolated between the knots. A curve that steps makes a binding a threshold; one that eases makes it an envelope. nullptr is the straight line.
