            // Track where we are after scale
            Vector2 mousePositionAfterScale = Vector2.Transform(mousePos, Matrix.Invert(camera.Matrix));

            // Adjust screen position with respect to scale to achieve zoom to Mouse cursor functionality
            camera.Move(mousePositionAfterScale - mousePositionBeforeScale);
