SDL_DisplayFormat - Convert a surface to the display format
SDL_Surface *SDL_DisplayFormat(SDL_Surface *surface);
This function takes a surface and copies it to a new surface of the
pixel format and colors of the video framebuffer, suitable for fast
blitting onto the display surface. It calls SDL_ConvertSurface
If you want to take advantage of hardware colorkey or alpha blit
acceleration, you should set the colorkey and alpha value before
calling this function.
If you want an alpha channel, see SDL_DisplayFormatAlpha.
If the conversion fails or runs out of memory, it returns NULL
