sdlxBlitSurfaceTiledWithScale function surface

bool sdlxBlitSurfaceTiledWithScale(Pointer<SdlSurface> src, SdlxRect? srcrect, Pointer<SdlSurface> dst, SdlxRect? dstrect, { double scale = 1.0, int scaleMode = SdlkScalemode.invalid, })

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 true on success or false on failure; call SDL_GetError() for more information.

\threadsafety Only one thread should be using the src and dst surfaces at any given time.

\since This function is available since SDL 3.2.0.
