From 4b8df221acc3bd3e681357df912bdbc7a1ce6c3f Mon Sep 17 00:00:00 2001
From: Bjørn Lindeijer <bjorn@lindeijer.nl>
Date: Thu, 23 Aug 2007 13:43:17 +0000
Subject: Removed two useless popup related methods, used generic close button
 functionality for the debug window and renamed Particle::mVector to
 Particle::mVelocity for clarity.
