Scale should only have an effect if autoscale is disabled, so that is not

That was wrong.

I think zoom affects the (requested) video window size, while scale
affects the video area size within the video window. Zoom is intended for
use with autoscale, which is enabled by default. Using both zoom and scale
simultaneous makes little practical sense, so it is theoretically possible
to define it (zoom affects the window, scale affects the video area).
