gwDrawing: translate, rotate ?

Hey there,

when using any gwDrawing methods to draw in screen space, like

 gw.wPolyline #([50,50,0], [200,150,0]) true rgb:#(red,red)

and I am happy with all the things I have drawn: Is there any way to globally translate and rotate this stuff? Like in Processing, which has pushMatrix() and popMatrix() commands, that can be used to apply transformation to everything. There are options to set the matrix for the gw methods
 gw.setTransform <matrix3>  
and I tried to mess around with it, but it does not seem to have any effect.
Any ideas?
