save_gif does not take draw.AnimateTransform('translate', ... into account

[francoisschwarzentruber]

I have tried to use drawsvg which is very nice. Thank you for the library!
The function draw.AnimateTransform works with save_svg meaning that I see the animation of the transformation, e.g. a translation. However, it does not work with save_gif: the image remains static.
Is it normal?
