What should happen when you close a dv3d canvas?

I don't know if the following behavior is a bug or a feature, but closing a dv3d canvas works 'strangely'!

If I create a dvd3 canvas and work with it after using x.interact() and then try to close the canvas by clicking on the 'X' at the top right of the canvas (in my xfce window manager), I go back to the python interpreter, but the canvas stays open.

I have mixed feelings about that because:

• on one hand, I expect a a window to close when I click on the close button
• on the other hand, being able to go back to the python shell and then start x.interact() again is useful, and this is a nice workaround for (q)uit does not work correctly in a DV3D interactive canvas (exits python) #953. Maybe we can remove this behavior once issue 953 is solved for sure?

There is also a possible real bug: when I'm back in the python shell after clicking on the canvas close button, and I click a second time on the dv3d canvas close button, the canvas still stays open, but I can't go back to interactive mode by typing x.interact(): nothing happens, I just stay in the python shell

If I open a second y dv3d canvas, and plot to it, and do a y.interact(), I can interact with y, but I also gain back the control of the x canvas. And I have to click 2 times in both of the canvas windows close button to lose control of the canvases.

And there is also the problem that nothing happens when I call the close() method a the dv3d canvas: I get a closing! debug message that should probably be removed, but the canvas stays open

>>> x.close()
Closing!
>>> y.close()
Closing!

@jypeter As far as the y.interact() giving you access to x, that's expected behavior. There's no way to discriminate between multiple canvases at this time.
