Member Function Documentation
   void SoContextHandler::destructingContext (uint32_tcontextid) [static]
       This method must be called by client code which destructs a context, to guarantee that there are no memory leaks upon context destruction.

       This will take care of correctly freeing context-bound resources, like OpenGL texture objects and display lists.

       Before calling this function, the context must be made current.

       Note that if you are using one of the standard GUI-binding libraries from Kongsberg Oil & Gas Technologies, this is taken care of
       automatically for contexts for canvases set up by SoQt, SoWin, etc.

   void SoContextHandler::addContextDestructionCallback (ContextDestructionCB *func, void *closure) [static]
       Add a callback which will be called every time a GL context is destructed. The callback should delete all GL resources tied to that
       context.

       All nodes/classes that allocate GL resources should set up a callback like this. Add the callback in the constructor of the node/class, and
       remove it in the destructor.

   void SoContextHandler::removeContextDestructionCallback (ContextDestructionCB *func, void *closure) [static]
       Remove a context destruction callback.
