From 17b2b06633729f1826715c1d0b84614aa3cedb3a Mon Sep 17 00:00:00 2001 From: Guido Günther Date: Mon, 28 Feb 2022 13:49:32 +0100 Subject: seat: Allow to cancel touches After cancelation we destroy the touch points associated with this surface as the Wayland spec says: No further events are sent to the clients from that particular gesture. Touch cancellation applies to all touch points currently active on this client's surface. The client is responsible for finalizing the touch points, future touch points on this surface may re-use the touch point ID.
