It looks like mouse-wheel-scroll-amount still makes some sense
as using wheel-scrolling to change the amount of font pixels.
Generally it's better to refrain from renaming old customisable
variables when possible.

Alas, that was never merged, but I still miss this functionality.
Maybe now there is another chance first to implement ((control) . text-scale)
and then duplicate the same functionality for ((shift) . (hscroll . 1))

These are more about changing the numeric values for smoother scrolling,
I already customized to the suggested values, and scrolling is really
smoother, but I'm not sure about changing the default values.
