The scale_x and scale_y parameters to QueueGeometry need to be applied to the geometry coordinates. Without this, the SDL_RenderSetLogicalSize() would not properly work on the renderer.
Note that a similar scale does not need to be applied by the backend in the other draw functions (line, fill, copyrect), because the coordinates are already scaled then.
