[ANNOUNCE] xf86-input-synaptics 1.8.99.1

[Peter Hutterer]

The first snapshot for synaptics 1.9 is now available.
A bunch of patches that have been sitting on git master for quite a while
now but many of these have been ported over to the 1.8.x stable releases.

Perhaps the most (in)significant change in this release is that we dropped
touch events from the driver. Previously, when all in-driver gestures like
two-finger scrollings were disabled, the driver would send touch events for
other fingers than the pointer-controlling finger. This, in technical lingo
is called a Really Bad Idea, but luckily (and somewhat expectedly) no-one
seems to have actually used it since the whole client-stack would have to
support touch events.
Dropping the events makes things more maintainable at virtually no loss of
features and allows us to address other issues with the driver in the past
that we could not do while the touchpad had to look like an absolute touch
device.

A new short delay before the second button click makes double tapping more
reliable, previously some applications ignored those events as they had the
same timestamp as the previous event.

The custom trackpoint button handling for the Lenovo *50 series has been
removed. The kernel handles those correctly now and since you need kernel
patches for those devices to work properly anyway there is no need for us to
keep a half-way solution around.

If a finger moves by more than 20mm within one scanout frame, we discard the
motion. This should alleviate cursor jumps that are seen when the kernel
driver loses track of the correct slot position. The fixes should still go
into the kernel, but this makes things more bearable in the meantime.

And a couple of other fixes that have been sitting on master for over a
year.

Gabriele Mazzotta (7):
      Prevent two-finger taps from being ignored
      Use cumulative relative touch movements while scrolling
      Use ABS_MT events for the palm detection when supported
      Don't assume that touch devices report per finger width and pressure
      Remove FastTap leftovers
      Update machine state diagram
      Add a delay between the second button down-up event of double taps

Peter Hutterer (22):
