Message:

From Martin Scheffler, "osgParticle: method to set start and end tile for particle texture (for animated particles). I also updated examples/osgParticle to show the feature.
The texture in data/Images should be copied to osg-data. I created the texture myself with the help of an explosion generator, so no license issues there.
