Hi,
I came across an issue when turning on anti-aliasing.
    _MyChartControl.Settings.ShapeRenderingMode = ShapeRenderingMode.AntiAlias;
I am displaying a colored wireframe surface.
    _MySurfaceSeries.FillMode = SurfaceFillMode.None;
    _MySurfaceSeries.FrameColorMode = SurfaceFrameColorMode.CustomColors;
    _MySurfaceSeries.FrameMode = SurfaceFrameMode.Mesh;

With ShapeRenderingMode set to ShapeRenderingMode.None things work as expected.  When set to ShapeRenderingMode.AnitAlias no mesh is drawn.  The axes and other components are drawn.

This was confusing and I tracked down a resolution.
I was setting the color of each vertex by using:
    uint[] gridColors = _MySurfaceData.Colors;
    gridColors[XXX] = YYY;
But if I instead use
    _MySurfaceData.SetColor(XXX);
The problem goes away.

Why does the mesh fail to display when turning on anti-aliasing and directly setting the color array value?  Is this a bug?
