From fb66405f4f8ee200a443e22d3b4f56a0e917f785 Mon Sep 17 00:00:00 2001
From: Manuel Bachmann <mbc@iot.bzh>
Date: Wed, 30 Sep 2015 05:22:25 +0200
Subject: [PATCH] Backport to Wayland/Weston 1.9.0 > 1.5.0.
Downgrade requirements to Wayland/Weston 1.9.0 > 1.5.0.
"wl_display_roundtrip_queue()" did not exist at the time,
so just use the wrapper functions instead.
Signed-off-by: Manuel Bachmann <manuel.bachmann@iot.bzh>
