WMF Images

We are using WMF IMages as the background for some Nodes.

This is the constructor code from my GoTextNode:
GoImage s = new GoImage();
s.Image = Properties.Resources.Start_Finish;
s.Selectable = false;
this.Background = s;
Below is the image I am assigning to the back ground. You can see how smooth it is yet when I look at it in Go Diagram it's not so nice. Is there something special I should be doing?

WMF files are scalable vector graphics. When read ia WMF nto an image at a specified size, it becomes bits, with dithering, etc. When you zoom back in, you’re not going to get the nice smooth vector graphics, you’re going to get scaled bits…

Does it look that bad at a normal size?
