[PATCH xf86-input-synaptics 0/8] Various clickpad improvements

[Hans de Goede]

Hi Peter, Benjamin et al,

The following patchset is the result of me playing with the clickpad on the
T440s and trying to make using it a more pleasant experience

Patch 1: "Add another third state to TouchpadOff for disabling all but button clicks"
Is from bugzilla, I've added this as one of my patches conflicts with it, and
it seems ready to go upstream.

Patch 2: "Add secondary (top) software buttons area"
Is also from bugzilla, some of my patches depend on it, and it too seems ready
to go upstream.

Patch 3-4 are some cleanup patches

Patch 5 is a resend of my earlier "Don't report motion inside soft-button areas"
patch, addressing Peter's review comments. I had to make it less effective
then before, now it only ignores motion started inside soft-button areas
before a click. After a click we switch to cummulative mode, so the coordinates
are no longer really absolute and still ignoring motion which seems to be
inside the soft-button area then breaks click + drag behavior.

Still this is a useful patch to have as it avoids accidental cursor movement
before the click.

Patch 6: "Ignore motion the first X ms after a clickpad click"
Is a new patch addressing accidental movement during and after the click,
this fixes my #1 anoyance with clickpads, where 2 out of 3 clicks turn into
a click + drag unless I hold my finger really really still.

Patch 7: "On button down update cumulative to current x and y, instead of previous"
Is hard to summarize, see the patch itself.

Patch 8: "Wait for *new* coordinates on a clickpad click before reporting the click"
Is equally hard to summarize, and may be somewhat controversial, which is why
I made this the last patch in the set :)

Regards,

Hans
