SDL_RenderClear - Clear the current rendering target with the drawing color.

       This function is available since SDL 3.2.0.

       This  function  clears  the  entire rendering target, ignoring the viewport and the clip rectangle. Note,
       that clearing will also set/fill all pixels of the rendering target to current renderer  draw  color,  so
       make sure to invoke SDL_SetRenderDrawColor() when needed.
