From f02ac2f82a0342c3e548a81950734b4bce383b7d Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Fri, 29 Jan 2010 07:58:13 +0000
Subject: Improved/quicker/easier handling of control port ranges.

 * Add "Set minimum to current value", "Set maximum to current value",
   and "Reset range" to control port context menu.

 * Only serialise properties (e.g. lv2:minimum) if they differ from
   the meta object's (prototype's, e.g. plugin) value.
