SDL_AddSurfaceAlternateImage - Add an alternate version of a surface.

       This function is available since SDL 3.2.0.

       This  function  adds  an  alternate  version  of  this  surface,  usually  used for content with high DPI
       representations like cursors or icons. The size, format, and content do not need to  match  the  original
       surface, and these alternate versions will not be updated when the original surface changes.

       This  function  adds a reference to the alternate version, so you should call SDL_DestroySurface() on the
       image after this call.
