[PATCH weston v2 2/2] libweston-desktop/xdg-shell: Properly handle ack_configure
Quentin Glidic
sardemff7+wayland at sardemff7.net
Tue Jul 18 11:14:49 UTC 2017
From: Quentin Glidic <sardemff7+git at sardemff7.net>
Now we keep track of serial->state association and we discard the states
that the client ignored.
