Some semi-mt model touchpads have a better accuracy for slot 0 then for slot 1 (they only have 2), so on semi-mt models only use the movement of the touch in slot 0 for 2fg scrolling, rather then the average movement of the 2 touches. This fixes 2fg scrolling being choppy / jumpy in some cases. BugLink: https://bugs.freedesktop.org/show_bug.cgi?id=89683 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Also needed: change the touchpad scroll source test to use more separate events. The current litest semi-mt touch implementation only moves the first touch on every second move. With 5 movements this isn't enough to fill the motion history and generate events, so double it to 10 so we're guaranteed to get scroll events.

/*!@mainpage libinput ======== libinput is a library that handles input devices for display servers and other applications that need to directly deal with input devices. It provides device detection, device handling, input device event processing and abstraction so minimize the amount of custom input code the user of libinput need to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating pointer events from touchpads, pointer acceleration, etc. libinput originates from weston, the Wayland reference compositor. The source code of libinput can be found at: http://cgit.freedesktop.org/wayland/libinput For more information, visit: http://www.freedesktop.org/wiki/Software/libinput/ Bugs can be filed in the libinput component of Wayland: https://bugs.freedesktop.org/enter_bug.cgi?product=Wayland&component=libinput Online API documentation: http://wayland.freedesktop.org/libinput/doc/latest/modules.html */
