Automation -> Type -> Waveform outputs values outside the minmax range

[salkin-mada]

- Tested with Sin,
when making an automation with waveform Sin the automation outputs between -1.0, 1.0
nevertheless that the automation min max range is set to 0.0 and 1.0
instead of offsetting it clips the 0.0, -1.0 values
the result is a clipped Sinus wave

- Triangle, Square, Saw may or may not have the same bug. Needs to be tested
