Detailed Description
A placeholder for a soundstate. The transformation is updated automatically during update traversal.
This class implements a scenegraph node has a SoundState associated to it. During cull traversal the orientation and position in world coordinates is calculated for this node and fed to the SoundSystem. This ensures that the node follows any transformation above this node.

Member Data Documentation
: The SoundState should be referenced with a ref_ptr, This currently causes problem, as the soundstate, and therefore any referenced soundsources are held, until this node is deleted. Which can be by OpenSceneGraph model cache. The time of this event can be late, outside the scope of main. This causes problems with OpenAL, which for some reason reports an invalid context during the deletion of that source. Therefore, just an ordinary pointer. Memory is properly deallocated by the SoundManager, so its not really a problem.
