the SDL_Surface structure to be copied from.
the SDL_Rect structure representing the rectangle to be copied, or NULL to copy the entire surface.
the SDL_Surface structure that is the blit target.
the SDL_Rect structure representing the target rectangle in the destination surface, or NULL to fill the entire destination surface.
the SDL_ScaleMode to be used.
true on success or false on failure; call SDL_GetError() for more information.
Threadsafety: The same destination surface should not be used from two threads at once. It is safe to use the same source surface from multiple threads.
Perform a scaled blit to a destination surface, which may be of a different format.
