There; now we're getting somewhere! ;-)


Seriously, are there any serious obstacles in the internals of SDL WRT 
supporting triple buffering on targets that can do it?

It would just be a new flag, and only a "suggestion". That is, SDL may 
still give you a single + shadow or double buffer screen , if triple 
buffering isn't possible. New applications running on older SDL versions 
would simply think that triple buffering isn't available, so there's no 
binary level API compatibility problem here.

Of course, it would be nice if the new flag is passed on to the resulting 
surface, if triple buffering is actually used, so that "smart" 
applications that do partial updates can know how many buffers there 
actually are.
