Taking the last 4 points means factoring in a coordinate that may be more than
40ms in the past - or even more when the finger moves slowly and we don't get
events for a while. This makes the pointer more sluggish and slower to catch up
with what the finger is actually doing.

We already have the motion hysteresis as a separate item to prevent jumps (and
thus adds some delay to the movement), the calculation over time doesn't
provide enough benefit to justify the sluggish pointer.

The hysteresis cuts the first pointer motion by the hysteresis margin. On some
touchpads this causes the tests to fail when the motion history length is
reduced (future patch). Allow the first event to be smaller than the expected
minimum.

This doesn't trigger in current tests because the hysteresis is per-event and
by the time we get past the minimum 4 events to move the pointer, we're
already flying unaffected by the hysteresis.

The test is supposed to make sure no motion event is sent and that scrolling
continues once leaving the edge. It does so by moving down the edge, into the
touchpad, then down further. The move from the edge into the touchpad had a
vertical component to it though and could cause the scroll minimum test to
fail. This is currently covered up by the delta calculations though, but fix
it anyway.

This doesn't have an effect in our current tests because the touchpad always
needs 4 motion events to get moving. But for the future, it simplifies the
case of "i want to move between x1/y1 and x2/y2", because it fills in only the
events in between rather than re-using the touch down coordinates and thus not
causing a motion on the first event.

to miss three-finger actions (we don't look at BTN_TOOL_TRIPLETAP if we have
3 or more slots).

Not all mice have a click angle with integer degrees. The new
MOUSE_WHEEL_CLICK_COUNT property specifies how many clicks per full rotation,
the angle can be calculated from that.

See https://github.com/systemd/systemd/pull/4440 for more information

CLICK_COUNT overrides CLICK_ANGLE, so we check for the former first and then
fall back to the angle if need be. No changes to the user-facing API.

Same as the HP Compat 8510, it doesn't send BTN_TOOL_DOUBLETAP/TRIPLETAP. This
may be a general issue with those series but they're 6 years old now, so
it's questionable to spend extra effort detecting them.
