Converts a VideoClip into an animated GIF using ImageMagick or

Parameters
-----------
filename
Name of the resulting gif file.
fps
Number of frames per second (see note below). If it
isn't provided, then the function will look for the clip's
``fps`` attribute (VideoFileClip, for instance, have one).
program
Software to use for the conversion, either 'ImageMagick' or
'ffmpeg'.
opt
(ImageMagick only) optimalization to apply, either
'optimizeplus' or 'OptimizeTransparency'.
fuzz
(ImageMagick only) Compresses the GIF by considering that the
colors that are less than fuzz% different are in fact the same.
Notes
-----
The gif will be playing the clip in real time (you can
only change the frame rate). If you want the gif to be played
slower than the clip you will use ::
>>> # slow down clip 50% and make it a gif
>>> myClip.speedx(0.5).to_gif('myClip.gif')
