tried it. Looks fine.

It is noteworthy, that minimize animations in general require participation from the panel client, to tell the compositor where the minimize target is, within the panel. This way, the compositor knows where to animate the minimizing surface. Specifically, the panel client must call zwlr_foreign_toplevel_handle_v1_set_rectangle() to set the geometry for the surface within the parent panel window.

Haven't looked into the details of how the animation works, I trust your videos which show how cool it is ;) So I have focused my comments on suggestions about the general Wayfire animation/transformer API.

Most probably there will be similar comments in your other animation PRs, so I will not review them until we're finished with this first one.

LGTM now, tested it and it works :)

One question which remains is what to do if the user minimizes without a minimize hint. The zoom animation will still animate the view, but as if it were closing. Wonder whether we can set a default minimize hint to be something like one of the corners of the screen?

With waybar, apparently not setting the minimize hint results in the view just disappearing during the animation. I was thinking, if we get 0's for the hint or it's otherwise not set, we could try to target minimizing to mouse pointer. Compiz did it, but I'm not sure the wayfire code would work for this.

Following the pointer could be nice, but if it doesn't work well enough, we can just pick a random target .. That will be better than the view just disappearing, at least the user has a visual indication of what happened.

Why not do what the default minimize animation did? If the minimize hint is not set, then the view would minimize to the center of the screen.

Sounds like it might work.

I tinkered with this and it seems the 'best' option was to minimize to the bottom center of the output.

LGTM now, thanks!
