From 7e685af06db0eab9a86d42c8bc4f6a26afe602ab Mon Sep 17 00:00:00 2001
From: Olivier Fourdan <fourdan@xfce.org>

Subject: Avoid spurious configure

Apps supporting extended XSync counter may update their XSync counter
which can cause spurious window reconfigure.

Add a flag to indicate if we ought to allow these reconfigurations.
