Issue:
SignalXY does sometimes not render on high density data when only partial data should be rendered due to X axis limits.

When changing the X axis limits just slightly (e.g. by panning) the signal renders fine:

The interpolation of the PointBefore results in a infinite Y value which eventually results in a overflow exception (which is handled by ScottPlot):

System.OverflowException: Overflow error.
   at System.Drawing.Graphics.CheckErrorStatus(Int32 status)
   at System.Drawing.Graphics.DrawLines(Pen pen, PointF[] points)
   at ScottPlot.Plottable.SignalPlotXYGeneric`2.Render(PlotDimensions dims, Bitmap bmp, Boolean lowQuality)
   at ScottPlot.Plot.RenderPlottables(Bitmap bmp, Boolean lowQuality, Double scaleFactor)

Reproducing:

double[] ys = new double[10000];
double[] xs = ys.Select(x => double.PositiveInfinity).ToArray();
double r = 0.0;
for (int i = 0; i < ys.Length; i++)
{
    r += 0.005;
    xs[i] = r;
    ys[i] = Math.Sin(r);
}
var signalXY = WpfPlot.Plot.AddSignalXY(xs, ys);
WpfPlot.Plot.AxisAutoY();
WpfPlot.Plot.XAxis.Dims.SetAxis(min: r - 10.0, r);
WpfPlot.Plot.Validate(deep: true);
WpfPlot.Refresh();
