Sprites are now rendered directly, rather than being blitted to a master surface which is then copied to a texture. Every sprite now carries an SDL_Texture in addition to an SDL_Surface (we need both, since SDL_Texture doesn't give read-access to the pixel data). All of the image-manipulation code is now in sdl_draw.c, and the DrawGraph_* functions are now wrappers. Some games (Daibanchou at least) use an API other than SACT2/DrawGraph, so these operations should be generic to avoid duplication.
