       SDL_MapRGBA - Map a RGBA color value to a pixel format.


       #include "SDL.h"

       Uint32 SDL_MapRGBA(SDL_PixelFormat *fmt, Uint8 r, Uint8 g, Uint8 b, Uint8 a);


       Maps  the  RGBA color value to the specified pixel format and returns the pixel value as a
       32-bit int.

       If the format has a palette (8-bit) the index of the closest matching color in the palette
       will be returned.

       If  the  specified pixel format has no alpha component the alpha value will be ignored (as
       it will be in formats with a palette).


       A pixel value best approximating the given RGBA color value for a given pixel  format.  If
       the  pixel  format bpp (color depth) is less than 32-bpp then the unused upper bits of the
       return value can safely be ignored (e.g., with a 16-bpp format the  return  value  can  be
       assigned to a Uint16, and similarly a Uint8 for an 8-bpp format).
