python and python3 gets to the root = Tk(), has same error. The rebuilt
P3 pillow, duh, rebuild the P2 version too dummy. And it works, I have
video from the camera! in python2!
But the bottom of the image is clipped at aproximately the 5cm mark on
the vertical ruler. The window is bigger, but the image is still
clipped. The crosshair target is at
nominally 8.2 vertically and the horizontal ruler is off screen due to
the clipped bottom. The only mode that is centered if 640x480.
Everythng else is clipped to some degree. I will probably make 640x480
the default in that case.
Even at 640x480, the reported FPS is .5, pretty slow. I'll go see how it
works with the machine live. I have another edgeing strip to put on a
panel anyway.

Both versions are installed.

So is Tk.

And that fails, I think from the pillow install message, it needs
TclTk-8.5 and wheezy only has 8.4. I'll re-enable backports and see if
it shows up. Except I must have clean house in that list. Then Tk IS
8.5 but the devel stuff wasn't, installing now. Aha, that was the magic
twanger!
