AddPicture doesn't set height

[jcoliz]

Here's a failing test:

    [Test]
    public void AddPicture_sets_dimensions()
    {
        // Arrange
        var pres = new Presentation();
        var shapes = pres.Slides[0].Shapes;
        var image = TestHelper.GetStream("test-image-1.png");

        // Act
        shapes.AddPicture(image);

        // Assert
        var picture = (IPicture)shapes.Last();
        picture.Width.Should().Be(300);
        picture.Height.Should().Be(300);
    }

This fails because picture.Height is erroneously 0.

  Failed AddPicture_sets_dimensions [54 ms]
  Error Message:
   Expected picture.Height to be 300, but found 0 (difference of -300).

Only workaround I have right now is to load the image in FIRST as a bitmap to measure it, then load it in AGAIN as a shape. Would be happy to hear if there is another workaround to do this in a single load.
