Changeset 7968 for OpenSceneGraph/trunk/src/osgPlugins/ive/AutoTransform.cpp

Message:

To osg::AutoTransform? added support for MinimumScale?, MaximumScale? and AutoScaleTransitionWidth? parameters
and a new scheme for computing the scaling when using autoscale that introduces smooth
transitions to the scaling of the subgraph so that it looks more natural.
