From 6f4460aee9962a49ae872eef42ba75a439ea6e59 Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Fri, 25 Jan 2008 06:55:57 +0000
Subject: Overhaul SLV2 API to return/take SLV2Value (instead of strings or
 primitives) wherever possible. Make 'index' a fundemental property of ingen
 ports.
