<viewpoint>.setclip

[mdebrecht]

I like the new interface to VRUT. Good Job! I just have a few quick questions:

It seems that when I try to clip a seperate viewpoint, the whole screen goes black. Similar code works for vrut, but doesn't seem to work with viz. Do you know what may be going wrong?

------------------------------------
import viz

viz.go()
viz.add('Layout.wrl')

window = viz.addwindow()
window.setposition(0, 380)
window.setsize(100, 100)

view = viz.addviewpoint()
window.setviewpoint(view)
view.setclip(0,40)

------------------------------------

Also, I noticed that Tkinter isn't included in viz's built-in python library. Do you know of a good way to import Tkinter?

Thanks,
Matthew
