Bug with DisplayConduit

Hi, I think there is a bug in rhinocommon’s DisplayConduit, more precisely in Protected Overrides Sub PreDrawObject(e As DrawObjectEventArgs).

When I use this:

    Dim pt = New Rhino.Geometry.Point3d(location.X, location.Y - 10, location.Z)
    e.Display.Draw2dText("TextContent", Color.Black, pt, True, True, "Arial")
    e.Display.DrawPoint(pt)

the “dot” is displayed with no text but still sized according to the text. When the associated object is selected the text appear, and disappear when unselected.

When I use this:

Dim MyTextDot As New Rhino.Geometry.TextDot("TextContent", New Rhino.Geometry.Point3d(location.X, location.Y + 10, location.Z))
            MyTextDot.FontHeight = FontHeight
            e.Display.DrawDot(MyTextDot, DisplayColor, Color.Black, BorderColor)

the text never shows.

I tried using the same code in other subs such as Protected Overrides Sub PostDrawObjects(e As DrawEventArgs) and it works.
