What exactly do the tscale-window, tscale-clamp and tscale-radius options do?

I've read the docs but I don't really get it.

--tscale-window lets you specify a custom windowing function for the tscale's kernel. If you aren't really sure what a "windowing function" is then you should probably leave these alone as as the defaults are very good. --tscale-radius likewise fine-tunes the scale radius in the temporal domain.

--tscale-clamp=1.0 (the default) prevents negative values from being used as weights in the scaling convolution kernel, which is particularly useful to prevent temporal ringing (i.e. you might see quick flashes otherwise).

Well, what do you expect, that the mpv manual should explain the entire DSP terminology? It's already long enough, you can't fit in everything..
