  • Readded smooth camera movement (configurable through CameraPosition), works also with camera-position-changes
  • Added free mouse look (press left control key)
  • Made strength of boost-blur configurable
  • Property svn:eol-style set to native
  • Property svn:mergeinfo set to (toggle deleted branches)
