oxyplot: LineSeries has bad performance with large amount of data due to `aliased=false`

When plotting large amount of data (i.e. over 100k points) using LineSeries, it has bad perfomance and showing up with long seconds delay. (environment: .net 4.5.2 WindowsForms on Windows 7 (x64))

I figured out that this issue is due to rc.DrawClippedLine(…, aliased=false, …) in LineSeries.RenderLine(). Unfortunately aliased=false is hardcoded.

There is a workaround making delived class with overriding RenderLine().

public class MyLineSeries : LineSeries
{

    List<ScreenPoint> outputBuffer = null;

    public bool Aliased { get; set; } = true;

    protected override void RenderLine(IRenderContext rc, OxyRect clippingRect, IList<ScreenPoint> pointsToRender)
    {
        var dashArray = this.ActualDashArray;

        if (this.outputBuffer == null) 
        {
            this.outputBuffer = new List<ScreenPoint>(pointsToRender.Count);
        }

        rc.DrawClippedLine(clippingRect,
                           pointsToRender,
                           this.MinimumSegmentLength * this.MinimumSegmentLength,
                           this.GetSelectableColor(this.ActualColor),
                           this.StrokeThickness,
                           dashArray,
                           this.LineJoin,
                           this.Aliased,  // <-- this is the issue
                           this.outputBuffer);

    }
}

I made a test program to compare performance, attached. CheckLineSeriesAliased.zip Here is a result with 10k, 20k, 50k, 100k data / aliased=true or false.

length	true	false
10k	0.02[s]	0.36[s]
20k	0.04[s]	1.05[s]
50k	0.09[s]	8.51[s]
100k	0.19[s]	64.83[s]
