LightResize and ImageResizer produce different output with FitMode.Crop

[stakx]

Given this test.jpg:

And the following code (which references NuGet packages ImageResizer and LightResize):

ImageResizer.ImageBuilder.Current.Build("test.jpg", "test-resized-imageresizer.jpg",
    new ImageResizer.Instructions
    {
        Scale = ImageResizer.ScaleMode.Both,
        Mode = ImageResizer.FitMode.Crop,
        Width = 240,
        Height = 200,
    });

LightResize.ImageBuilder.Build("test.jpg", "test-resized-lightresize.jpg",
    new LightResize.Instructions
    {
        Scale = LightResize.ScaleMode.Both,
        Mode = LightResize.FitMode.Crop,
        Width = 240,
        Height = 200,
    });

The two resized images appear to be stretched differently in the vertical direction:

This appears to happen only when the image will be cropped vertically.

Investigate what is the cause of this difference (coordinate rounding?), and whether it qualifies as a (minor) bug in LightResize.
