CropCircleWithBorderTransformation - border radius incorrect about glide-transformations

[fprt77]

Fixed transform function should look like this:

  @Override
  protected Bitmap transform(@NonNull Context context, @NonNull BitmapPool pool,
                             @NonNull Bitmap toTransform, int outWidth, int outHeight) {

    Bitmap bitmap = TransformationUtils.circleCrop(pool, toTransform, outWidth, outHeight);

    setCanvasBitmapDensity(toTransform, bitmap);

    Paint paint = new Paint();
    paint.setColor(borderColor);
    paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeWidth(borderSize);
    paint.setAntiAlias(true);

    int outMinEdge = Math.min(outWidth, outHeight);
    Canvas canvas = new Canvas(bitmap);
    canvas.drawCircle(
      outMinEdge / 2f,
      outMinEdge / 2f,
      outMinEdge / 2f - borderSize / 2f,
      paint
    );

    return bitmap;
  }
