Filling a Polygon with LinearLineSegment causes a strange line leaving the drawing

[zeroskyx]

The following code causes a strange line leaving the polygon to the right side:

`
using System.IO;
using System.Numerics;
using ImageSharp;
using ImageSharp.Drawing.Brushes;
using SixLabors.Shapes;

namespace Repro
{
	public class Program
	{
		public static void Run()
		{
			Vector2[] Points = new[]
			{
				new Vector2( 8, 8 ),
				new Vector2( 64, 8 ),
				new Vector2( 64, 64 ),
				new Vector2( 120, 64 ),
				new Vector2( 120, 120 ),
				new Vector2( 8, 120 )
			};

			using( Image ThisImage = new Image( 256, 128 ) )
			{
				ThisImage.Fill( new SolidBrush( new Color( 0xFF, 0xFF, 0xFF, 0xFF ) ) );

				ThisImage.Fill( new SolidBrush( new Color( 0x00, 0x00, 0x00, 0xFF ) ), new Polygon( new LinearLineSegment( Points ) ) );

				using( MemoryStream ThisBuffer = new MemoryStream() )
				{
					ThisImage.SaveAsPng( ThisBuffer );
					byte[] ThisByteArray = ThisBuffer.ToArray();
					File.WriteAllBytes( @"C:\Temp\Image.png", ThisByteArray );
				}
			}
		}
	}
}

`

The problem seems to be related to the fourth corner new Vector2( 120, 64 ) since slightly increasing the Y-coordinate no longer causes the line to appear: new Vector2( 120, 64.01f ):

The root cause of this bug was in the SixLabors.Shapes library.

This has now been fixed, if you update your ImageSharp.Drawing.Paths to 1.0.0-alpha2-00068 (which is just updates our SixLabors.Shapes dependency) then your issue is resolved.

The fix landed in SixLabors.Shapes 0.1.0-alpha0007
