This renders the given images into a video to view inside the Jupyter
notebook and/or save into a file.
@param image_files
Images to render into a video.
@param fps
Frames/images per second to show. Default is `5`.
@param callback
Optional callback called for each frame with the signature
`callback(i, ax, ctrl)`, where `i` runs from `0` through the frame
numbers, `ax` is the axes object, and `ctrl` the image control created
by `ax.imshow()`.
@param reverse
If `True`, play the images in reverse order.
@param dpi
Dots per inch of the stored image. When set correctly, the image will
be shown in its native resolution (i.e. without resizing).
@param interpolation
Pixel interpolation in case the rendered size is not exactly the image
size. Default is `None`.
@param repeat_first
Number of extra repetitions of the first image. This adds additional
time at the start. Default is `0`.
@param repeat_last
Number of extra repetitions of the last image. This adds additional
time at the end, so that the result can be inspected a little longer.
Default is `0`.
@param save
Optional filename for storing the resulting video.
@param repetitions
How often to repeat individual images. Should be a sequence of
integers corresponding to the individual images. Missing elements are
taken to be 1.
@param crop
4-tuple with the amount of cropping (in pixel) in order (left, botton,
right, top).
@param snap_first
If `True`, save a snapshot of the first frame.
