Summary: Gtk gets confused by wayland touch events
Classification: Platform
Product: gtk+
Version: 3.13.x

GNOME version: ---
When using a touchscreen under weston, Gtk+ sometimes seems to get confused
about its inputs. E.g. when running gtk3-demo, scrolling in the demo list with
the touchscreen causes mouse events to be ignored afterwards.
Some digging revealed that this is due to weston numbering its touch events
sequence from 0 and gdks wayland backend simply using GUINT_TO_POINTER to set
the touch.sequence field. This causes gdk_event_get_touch_sequence to return
NULL which confuses other parts of Gdk/Gtk.
