Changeset 514 for trunk/avango-osg/src/avango/osg/Node.cpp

Message:

getAbsoluteTransform function now accepts a second parameter which is the node to stop the traversal. This is useful in case you do not want to traverse the scenegraph up to its root node. Also added a function to query the maximal texture size.
