[news.eclipse.gef3d] Problem getting Draw3d to draw something

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

Hi,

I tried to wrap my head around Draw3d a bit and play around with it but
didn't managed to get a simple example working (I simply wanted to draw
a rectangle).

Could someone please correct the code from below for me?
