sdlBlitSurfaceUncheckedScaled function surface

bool sdlBlitSurfaceUncheckedScaled(Pointer<SdlSurface> src, Pointer<SdlRect> srcrect, Pointer<SdlSurface> dst, Pointer<SdlRect> dstrect, int scaleMode,)

Perform low-level surface scaled blitting only.

This is a semi-private function and it performs low-level surface blitting, assuming the input rectangles have already been clipped.

\param src the SDL_Surface structure to be copied from. \param srcrect the SDL_Rect structure representing the rectangle to be copied, may not be NULL. \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, may not be NULL. \param scaleMode the SDL_ScaleMode to be used. \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.
