I’m working (slowly) on multi‐touch support, which will hopefully
solve the problems with some fine pointing devices.

For example, the problem with the trackpad on macs is because macOS
sends an event for each two‐finger scroll movement, which can equate to
as little as a one pixel move. Emacs treats each of those events as a
whole line scroll.

The correct way to handle it is to add up the deltas until they’re
greater than or equal to a line‐height, then issue the scroll command.
