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.

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.

Remove a context destruction callback.
