Feature Request: animated GIF frame stepping

[mk-pmb]

Hi!
I like ImageZoom and use it a lot.
Since you're already tapping into images and have an image related context menu, could you maybe integrate frame stepping for animated GIFs there? Preferentially with only a checkbox toggle in the menu, and the stepping controls near or inside the image in latter case, visible only when hovered.
It seems there already is a GIF stepping extension using a shell, which of course is less convinient but might give hints on how to extract frames.
