From 58807f5840592959c31b415f7e2d64967594b5ee Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Wed, 18 Nov 2009 01:20:52 +0000
Subject: Less reliance on Buffer::type() (which doesn't really make sense,
 since buffer type != port type...). AudioBuffer copy improvements. Remove
 redundant AudioBuffer::_port_type (same as Buffer::_type).
