I'd suggest to implement it like the other render techniques are 
implemented (Start_Adaptive_Tracing() and Start_Non_Adaptive_Tracing()). 


And if you want to have a chance that someone else implements the 
frontend for the other platforms you seriously need a documentation of 
the interface between the core code and the platform specific part.  It 
might be a good idea to completely leave out the interactive part so you 
just need POV_DISPLAY_UPDATE_RECT and nothing more.
