shiftEdges
Shifts the rising and falling edges of a boolean profile independently of each other.
This allows for segments to not just be shifted around, but stretched or squished, or even deleted.
A rising edge is defined as the time just after a false segment ends - whether it meets a true segment or a gap. Similarly, a falling edge is just after a true segment ends.
Parameters
shiftRising
duration to shift the rising edges by
shiftFalling
duration to shift the rising edges by
