You can check also other fields of SDL_PixelFormat structure to get
R,G,B color components. Interesting field names are
Uint8 Rloss;
Uint8 Gloss;
Uint8 Bloss;
Uint8 Rshift;
Uint8 Gshift;
Uint8 Bshift;
Uint32 Rmask;
Uint32 Gmask;
Uint32 Bmask;
Or you can use SDL_GetRGB(Uint32 pixel, SDL_PixelFormat *fmt, Uint8 *r,
Uint8 *g, Uint8 *b) function which will probably do the dirty bit
shifting and masking work for you.
