From 25b610f12b8e46b48e8eda252d029da211ec6ad5 Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Fri, 27 Jul 2007 04:07:06 +0000
Subject: Control port slider functionality (when not in edit more, or holding
 down control). Known issue: Control modifier toggling currently only works
 when pointer on canvas (not a module or port).
