    BufferedImage tmp = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB);
    Graphics2D g2 = tmp.createGraphics();
    var imgOrigTransform = g2.getTransform();

    int canvasWidth = canvas.getWidth();
    int canvasHeight = canvas.getHeight();
    setupGraphics(g2, canvasWidth, canvasHeight, getText());
    var at = g2.getTransform();
    g2.setTransform(imgOrigTransform); // provideShape must be called with untransformed Graphics
    Shape shape = provideShape(g2, null, canvasWidth, canvasHeight);

    g2.dispose();

         *     needs to be shadowWidth wide, so that there is space for the
         *     shadow to be drawn.
         *  4) Draw the rounded rect as black, with an opacity of 50%
         *  5) Create the BLUR_KERNEL
         *  6) Blur the image
         *  7) copy off the corners, sides, etc into images to be used for
         *     drawing the Border
