Description

We're getting out of bounds exceptions when resizing with nearest neighbor. All other resamplers using the worker pipeline are fine.

I have a fix, which I will push soon. We were not using the interest working bounds properly.

Steps to Reproduce

[Theory]
[InlineData(1, 1)]
[InlineData(4, 6)]
[InlineData(2, 10)]
[InlineData(8, 1)]
[InlineData(3, 7)]
public void CanResizeNearestNeigbour(int width, int height)
{
    using (var image = new Image<Rgba32>(1, 1))
    {
        var size = new Size(width, height);
        image.Mutate(x => x
            .Resize(
                new ResizeOptions
                {
                    Size = size,
                    Sampler = KnownResamplers.NearestNeighbor
                }));

        Assert.Equal(width, image.Width);
        Assert.Equal(height, image.Height);
    }
}
