just use GUI scaling, and only IF the prior is too challenging

It's not as if a constantly changing single-axis non-linear transform is trivial to accomplish in the GUI either :(
You often want sample accurate waveform visualization when tuning samples that are time or pitch warped to set start and loop points at zero crossings to avoid clicks without needing fades.
Overwhelmingly, there's no such thing as a zero crossing. Your closest real world case is a point in time (between samples) where the previous sample is positive and next one is negative (or vice versa). However, by truncating the next sample to zero, you create distortion (and if the absolute value of the preceding sample is large, very significant distortion.
Zero crossings were an early myth in digital audio promulgated by people who didn't know enough.
Fades are always the best solution in terms of limiting distortion (though even then, they can fail in pathological situations).
