Changed the osg::Node::setUserData so that the data type has to be an
osg::Referenced, and removes the dependancy on osg::MemoryAdapter. I have
done this since it simplifies the OSG side of the interface and makes it
less like that the user might abuse the memory managment of the data. It
does however mean that user data will have by subclassed from Referenced,
and therefor may require users to have their own adapter to do this.
However, this little nuasance is worth the extra cleaness and robustness
afforded by going the osg::Referenced route.
should be applied to a node or its child with the new osg::Node::setCullingActive()
flag. A mechanism has been implemented so that if child has its culling disabled
then their parents, all the way up to the root are also have their culling
implicitly disabled.
The osg::CullVisitor has updated to take account of
both the explicit control via setCullingActive and the implicit culling
disabling through children being disabled.
This feature is useful for nodes which don't have a bounding volume to cull
against, earth sky implementations and light sources.
The default osg::Node::_cullingActive is true, i.e. culling is enabled by
default.
have the new ReaderWriter::Options* structure passed to them, which meant the
the virtual functions didn't bind with the new base class methods and wern't
called on a write.
for settings options in osgDB::Registry, and added the paramter to all of the
reaader/writer plugins. The Options structure by default has an string attached
for packing basic options, however, it also can be subclassed to encapsulate
any users defined option data. In the later case both the client code *and*
the plugin need to be aware of subclass, the plugin will need to use
dynamic_cast<> to assertain its type.
