From 23d74f838521320dc1682426341d1874061337a6 Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Thu, 26 Jul 2007 22:18:33 +0000
Subject: Make canvas grab events. Remove silly ctrl+click zoom event grabs.
 Add concept of "edit mode", old behaviour = edit mode, edit mode off = no
 connections or module moving.
