[ANNOUNCE] libinput 0.14.0

[Peter Hutterer]

A new release of libinput, 0.14.0, is now available. 

libinput now provides middle button emulation for physical buttons and, for
some devices, a configuration interface to enable said emulation.
The API is the usual quartett of configuration queries:
	libinput_device_config_middle_emulation_is_available()
	libinput_device_config_middle_emulation_set_enabled()
	libinput_device_config_middle_emulation_get_enabled()
	libinput_device_config_middle_emulation_get_default_enabled()

A new tool "libinput-list-devices" was added. This tool lists the locally
recognised devices and their respective configuration options and
configuration defaults. Example output:

    Device:         SynPS/2 Synaptics TouchPad
    Kernel:         /dev/input/event4
    Group:          9
    Seat:           seat0, default
    Size:           97.33x62.40mm
    Capabilities:   pointer
    Tap-to-click:   disabled
    Left-handed:    disabled
    Nat.scrolling:  disabled
    Calibration:    n/a
    Scroll methods: *two-finger
    Click methods:  *button-areas clickfinger

Note that due to the design of libinput, this tool can only show the
_default_ configurations, not the _current_ configuration of each device.

The pointer acceleration range has been widened to allow for greater
deceleration and greater acceleration. Since we retain the [-1, 1] range,
you may see a slight slowdown or speedup. To get the previous behaviour,
use the value: current setting * 2.0/3.0.

Five (or more) finger tapping is now handled correctly, though note we only
send events for up to three fingers. libinput now supports multi-tap and
drag, so e.g. three taps will execute a triple-click.

Palm detection now avoids accidental tapping, see
http://wayland.freedesktop.org/libinput/doc/latest/palm_detection.html

And of course the usual bugfixing, including letting libinput handle more
devices such as keyboards with scroll wheels or devices that only consist of
a wheel.

As usual, the shortlog is below.

Hans de Goede (8):
      Fix scroll-threshold check for edge-scrolling to use normalized coordinates
      Add a delta_coords type and use it were applicable
      Add a normalized_length helper function and use this where applicable
      Add a normalized_is_zero helper function
      Change tp_filter_motion to normalized_coords
      Rename delta_coords to device_float_coords
      Change vector_get_direction input to a normalized_coords struct
      filter: Make acceleration range wider
