From 40516c23f43aaf4ca785014dff596d8f66677de3 Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Sun, 12 Aug 2012 23:42:17 +0000
Subject: Use ingen:root as the path for the root patch, opening up path space
 for engine/driver/etc. Strict conversion between Path and URI (Path no longer
 is-a URI).

git-svn-id: http://svn.drobilla.net/lad/trunk/raul@4672 a436a847-0d15-0410-975c-d299462d15a1
