SDL_GetRGB - Get RGB values from a pixel in the specified format.

       This function is available since SDL 3.2.0.

       This  function  uses  the entire 8-bit [0..255] range when converting color components from pixel formats
       with less than 8-bits per RGB component (e.g., a completely white pixel in  16-bit  RGB565  format  would
       return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8]).

pixel  a pixel value.

               describing the pixel format.

              an optional palette for indexed formats, may be NULL.

       r      a pointer filled in with the red component, may be NULL.
