Point<double> getScale()

Get the drawing scale for the current target.

\param renderer the rendering context. \param scaleX a pointer filled in with the horizontal scaling factor. \param scaleY a pointer filled in with the vertical scaling factor. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.
