From 54e981f0d3599fc7413a30c00562b3ea789e2fe7 Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Fri, 5 Oct 2007 06:01:39 +0000
Subject: Fix ridiculous CPU chewing on embedded LV2 GUIs. For some reason the
 GUI widget's size request signal fires continuously... this needs fixing.
