[PATCH] Fix debouncing algorithm

The algorithm assumed that bouncing can only occur once when pressing a button. This approach did not work with my mouse because that is not 100% correct. Bouncing can occur at both the press and release events and can bounce multiple times. Also, the timeout period was missing more than 50% of

[PATCH weston v3 05/36] libweston: make wl_output point to weston_head

[PATCH weston v3 11/36] libweston: add weston_head::connected

From: Pekka Paalanen Heads may be disconnected or connected and the compositor needs to be able to know the state to know which heads to take into use. Currently a single head is automatically created with an output, and outputs are only ever created as connected

[PATCH weston v3 16/36] libweston: add weston_head_is_device_changed() API

[PATCH weston v3 02/36] libweston: introduce weston_head
