Hi Andreas, All,

I'm currently looking at making the singletons SceneFileHandler and 
ImageFileHandler replaceable with user derived types [1].
While looking at the current code I stumbled over the 
setReadCB/setWriteCB functions and I'm wondering what these callbacks 
are used for, if present they seem to take over the operation of the 
SFH/IFH ? What are use cases for these callbacks and could the same 
thing be done if there was a way to derive from SFH/IFH and override 
some functions ?

        Thanks,
                Carsten

[1] Basically there still would be a global SFH and IFH, but the SFH 
holds a pointer to the IFH it uses. By fixing up the uses of the global 
SFH/IHF in the Scene/ImageFileType objects and loader implementations it 
becomes possible to use also use ones own derived types for SFH/IFH and 
have them DTRT.
Comments/other ideas of course welcome :)
