[SDL] A question about SDL_DisplayFormat()...

you misunderstand( or else i do, and im then screwed )

AFAIK, the surfaces you load are left near enough to the state they were as 
a file on disk.

it is only when the blitting to the display surface occurs is conversion 
done and , again as far as i have gathered, the conversion is temporary and 
does not afffect the blitted surface.

this is needless to say, performance intensive.

the function 

my_fast_new_surface = SDL_DisplayFormat( my_crappy_old_surface );

copys the surface, so the original is again, untouched.

maybe i misread you, but i hope this helps
