Animated GIFs

I would like to display an animated gif in the bottom right hand corner of the screen. It is a throbber. However, none of the banners seems to work with animated gifs with transparency. Additionally, I am aware of the AnimGif plugin, but that does not apply at all since there is no NSIS install window/MUI.

I don't really see a reason why a plugin like this has not already been written. What will it take?

AnimGif parameter /hwnd sets target window for gif. If you can find desktop handle 😉 this is possible. But real transparency is not supported, plug-in only uses background color of the target window.
