Sending a snapshot to a file is easy; just press the "i" (for image) key. I
added this today (previously the "p" key was used, but that is a vtk keypress
event that cannot be turned off). Pressing "h" will display the keybindings.

It should be possible to use Viper from C++, but, in that case, a Python
interpreter must be embedded in a library somehow. I have never done this.
