The Pen is set in System.Drawing.Xsharp only if the class is 
a DrawingGraphics . The case where it can be an IToolkitImageGraphics is 
totally ignored.

But I don't see a fix yet :(

System.Drawing/Toolkit/ToolkitGraphicsImageBase.cs, selectedPen doesn't appear 
to be set to anything and setting it to base.Pen and attempting to cast it 
yields the same results. Someone else with better knowledge of how the toolkit 
is put together and operates might have better luck.
