Newt canvas working in Jzy3d

Hi,
I just would like to provide positive feedback concerning Newt canvas that has been easy to add to Jzy3d (with little help from Julien, thanks). Mouse and keyboard controllers work fine as well, so now you can call:
new Chart("newt")
to have a newt canvas to display your chart.

https://github.com/jzy3d/jzy3d-api/blob/master/src/api/org/jzy3d/plot3d/rendering/canvas/CanvasNewt.java

Only on the trunk, available for download for next version (1.0)

I just noticed the following System.err.println when closing the newt canvas... looks like a forgotten debug.
X11Util.Display: Shutdown (close open / pending Displays: false, open (no close attempt): 2/2, pending (not closed, marked uncloseable): 0)
X11Util: Open X11 Display Connections: 2
X11Util: Open[0]: NamedX11Display[:0, 0x9c5a458, refCount 1, unCloseable false]
X11Util: Open[1]: NamedX11Display[:0, 0x9ca0c08, refCount 1, unCloseable false]

Sweet, thank you!
Nope :)
This is a reminder for _you_ to close resources you have opened.

"open (no close attempt): 2/2" states that there are 2 X11 Display connections
open (probably one NEWT Window (GLWindow) with it's 2 X11 Display connections
for event polling and rendering.

If you would call glWindow.dispose() all would be fine.

If you close it but use the ATI proprietary driver,
you will see something similar but different:
"open (no close attempt): 0/0, pending (not closed, marked uncloseable): 2/2"

Meaning close has been issued by the user,
but JOGL has marked them uncloseable.
This is a workaround for an ATI driver bug.

Thanks for attention :)
A warning message suggesting the action to do (e.g. "call GLWindow.dispose() to avoid this warning") would be great for unexperienced users of newt.

Can't find a dispose() method on GLWindow neither GLPBuffer, but a destroy() method. Is that equivalent?

Nice to know you warn without failing :)
