       Miscellaneous Classes -

       class SoFieldContainer
           The SoFieldContainer class is a base class for all classes that
           contain fields.

       The classes containing fields in Coin are the node and engine classes,
       so they are all subclasses of SoFieldContainer. "
   class SoInput
       The SoInput class is an abstraction of file import functionality.

       This class takes care of most of the chores of doing data import in
       Coin. It puts a layer of abstraction over the read operations to make
       it transparent for the rest of the Coin code whether or not we’re
       reading from a file, from a memory buffer or from stdin. "
   class SoOutput
       The SoOutput class is an abstraction of an output stream.

       SoOutput offers the ability to write basic types to a file or a memory
       buffer in either ASCII or binary format. "
   class SoAuditorList
       The SoAuditorList class is used to keep track of auditors for certain
       object classes.

       This class is mainly for internal use (from SoBase) and it should not
       be necessary to be familiar with it for ’ordinary’ Coin use. "
   class SoBaseList
       The SoBaseList class is a container for pointers to SoBase derived

       The additional capability of the SoBaseList class over its parent
       class, SbPList, is to automatically handle referencing and
       dereferencing of items as they are added or removed from the lists. "
   class SoCallbackList
       The SoCallbackList is a container for callback function pointers.

       This list stores callback function pointers (along with user-specified
       extra data to pass to the callbacks) and provides a method for
       triggering the callback functions. "
   class SoPathList
       The SoPathList class is a container for pointers to SoPath objects.

       As this class inherits SoBaseList, referencing and dereferencing will
       default be done on the objects at append(), remove(), insert() etc. "
   class SoPickedPointList
       The SoPickedPointList class is a container for pointers to
       SoPickedPoint objects.

       This list class will delete the picked points when
       destructed/truncated, or when a picked point in the list is replaced by
       another picked point The caller is responsible for allocating the
       picked points passed to the list, but should not deallocate them since
       this will be handled by the list. "
   class SoTypeList
       The SoTypeList class is a container class for arrays of SoType objects.
   class SoAudioDevice
       The SoAudioDevice class is used to control an audio device.

       The SoAudioDevice class is responsible for initialization of an audio
       device, as well as enabling and disabling sound. It is a singleton
       class. "
   class SoBase
       The SoBase class is the top-level superclass for a number of class-

       SoBase provides the basic interfaces and methods for doing reference
       counting, type identification and import/export. All classes in Coin
       which uses these mechanisms are descendent from this class. "
   class SoChildList
       The SoChildList class is a container for node children.

       This class does automatic notification on the parent nodes upon adding
       or removing children. "
   class SoContextHandler
       The SoContextHandler class is for now to be treated as an internal
   class SoDB
       The SoDB class keeps track of internal global data.

       This class collects various methods for initializing, setting and
       accessing common global data from the Coin library. "
   class SoFullPath
       The SoFullPath class allows examination of hidden children in paths.

       SoPath allows only access from the head node to the first node with
       hidden children, but not any further. "
   class SoInteraction
       The SoInteraction class takes care of initalizing internal classes.

       SoInteraction is present for the sole purpose of providing an interface
       to the initialization methods of the classes in Coin which are somehow
       related to user interaction, like the draggers and manipulators. "
   class SoLightPath
       The SoLightPath class is a light version of SoPath.

       SoLightPath can be used if you only need a temporary path, and don’t
       want the overhead that comes with an SoPath (ref, unref, auditing etc).
   class SoLockManager
       The SoLockManager is a defunct software license lock mechanism.

       This is just a dummy implementation of the TGS Inventor class used to
       provide a license locking mechanism. Since Coin can be used without any
       royalty fees or client-site license locks, no such mechanism is needed.
   class SoNormalGenerator
       The SoNormalGenerator class is used to generate normals.

       FIXME: document properly. "
   class SoNotRec
       The SoNotRec class specifies records for notification lists.
   class SoNotList
       The SoNotList class is a list of SoNotRec notification records.
   class SoOffscreenRenderer
       The SoOffscreenRenderer class is used for rendering scenes in offscreen

       If you want to render to a memory buffer instead of an on-screen OpenGL
       context, use this class. Rendering to a memory buffer can be used to
       generate texture maps on-the-fly, or for saving snapshots of the scene
       to disk files (as pixel bitmaps or as Postscript files for sending to a
       Postscript-capable printer). "
   class SoPath
       The SoPath class is a container class for traversal path descriptions.

       SoPath objects contain a list of SoNode pointers and a list of child
       indices. Indices are necessary to disambiguate situations where a node
       uses the same node as a child multiple times. "
   class SoPickedPoint
       The SoPickedPoint class is used for specifying picked points.

       It holds miscellaneous information about the picked point, such as
       position, normal, texture coordinate and material index in the current
       material. It might also hold detail information (an SoDetail subclass)
       for every node in the picked path. "
   class SoPrimitiveVertex
       The SoPrimitiveVertex class represents a single vertex of a generated

       Instances of SoPrimitiveVertex are constructed when generating
       primitive data, primarily during an SoCallbackAction traversal.
       Depending on the context the vertex could represent a single 3D point,
       one of the two vertices in a line or one of the three vertices in a
       triangle. "
   class SoSceneManager
       The SoSceneManager class provides the main interface between the scene
       graph and the GUI toolkit.

       The renderarea class from the GUI toolkit you are using uses this class
       as the interface against the scene graph. Event handling and providing
       ’hooks’ to do rendering are the main functions of the class. "
   class SoState
       The SoState class manages the Coin scenegraph traversal state data.

       The SoState class is used by actions derived from the SoAction class.
       It manages the scenegraph state as stacks of elements (ie instances of
       classes derived from SoElement). "
   class SoTempPath
       The SoTempPath class is used to store temporary paths.

       The path simply turns off auditing in the constructor, and leaves the
       user with the responsibility of keeping the path valid. "
   class SoType
       The SoType class is the basis for the run-time type system in Coin.

       Many of the classes in the Coin library must have their type
       information registered before any instances are created (including, but
       not limited to: engines, nodes, fields, actions, nodekits and
       manipulators). The use of SoType to store this information provides
       lots of various functionality for working with class hierarchies,
       comparing class types, instantiating objects from classnames, etc etc.
