[SDL] Convert opencv IplImage * to SDL_Texture * (SDL 1.3)

[Alex Barry]

Well, if the most efficient way is to just use SDL_Surface stuff, I found
this link (
http://stackoverflow.com/questions/393954/how-to-convert-an-opencv-iplimage-to-an-sdl-surface)
that seems to have some value to it.
I think my biggest question is just how to proceed: with SDL_Texture or
SDL_Surface->SDL_Texture

If you have some code, though, that would be helpful :)
Thanks for the help
