https://code.google.com/p/jmonkeyengine/issues/detail?id=592#makechanges - Went the update targets and materials on each update, in practive it doesn't have a noticeable impact on performance. - Changed the way target meshes and materials were stored (arrays), for respectively a SafearrayList and a HashSet. This avoid instancing and copying arrays on each frames. - Also removed targets and materials from serialization as we don't care to save or load them now that they are gathered on each frame. git-svn-id: https://jmonkeyengine.googlecode.com/svn/trunk@10577 75d07b2b-3a1a-0410-a2c5-0572b91ccdca
