/**
* Perform a scaled and tiled blit to a destination surface, which may be of a different
* format.
*
* The pixels in `srcrect` will be scaled and repeated as many times as needed to completely fill `dstrect`.
*
* \param src the SDL_Surface structure to be copied from.
* \param srcrect the SDL_Rect structure representing the rectangle to be
* copied, or NULL to copy the entire surface.
* \param scale the scale used to transform srcrect into the destination rectangle, e.g. a 32x32 texture with a scale of 2 would fill 64x64 tiles.
* \param scaleMode scale algorithm to be used.
* \param dst the SDL_Surface structure that is the blit target.
* \param dstrect the SDL_Rect structure representing the target rectangle in
* the destination surface, or NULL to fill the entire surface.
* \returns 0 on success or a negative error code 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.
*
* \since This function is available since SDL 3.0.0.
