Is `pixel-scroll-precision-mode' supposed to be a drop-in replacement
for `pixel-scroll-mode'?  If yes, how close is it?

With `pixel-scroll-mode', I can see that when I scroll slowly, scrolling
behaves more like it would in Firefox (i.e., smooth rather than not
choppy).

With `pixel-scroll-precision-mode', I'm not sure I can spot any
difference with or without it enabled, when scrolling with the mouse
wheel.

I just found `pixel-scroll-precision-interpolate-page', which makes it
more attractive for me to use.  Is there a way to make it scroll faster
though?  If not, could we add such an option?

BTW, why isn't there a pixel-scroll defgroup under the scroll group
instead?  I tried `M-x customize-group RET pixel TAB' but couldn't find
anything relevant.
