feat: minimize window on suspend

[SyedAhkam]

What kind of change does this PR introduce?

A feature! Hooks into :suspend, interprets it as a Minimize request and minimizes the window.

Fixes: #1496

Did this PR introduce a breaking change?

No

First of all, thank you!

Then, I'm not entirely sure about the interaction which is done with the command here and the already existent g:neovide_fullscreen variable. The advantage I see behind the variable is that it's not necessary to keep track of the variable separately if a more special scripted behavior is desired. At the moment it even looks like it's not possible to return from the minimized state.

On the other hand it'd be also kind of fair to say that returning from minimization must be done through the user, or through platform specific APIs in a separately running script.

I just noticed that the UI protocol provides suspend https://neovim.io/doc/user/ui.html. So I think a better implementation is to hook into that, sorry for misleading you @SyedAhkam

[SyedAhkam]

In that case we do not need to expose a custom command right?

Also reading the documentation for suspend, it is mentioned that the behaviour of its invocation is implementation specific. I wonder if it is safe to interpret it as a minimize window request.

@SyedAhkam

That's correct, no custom command is needed, we just need to react to it, like we do for other UI events. The users can still bind :suspend to the keybinding they like, or even automate it if they want to.

I think for now, it's safe to assume minimizing the window. But I think the end goal would be to check if we started with --nofork and do a real suspend in that case on platforms that supports it. That would be especially handy for users of tiling window managers with terminals that swallow.

[SyedAhkam]

Thanks for the direction. I have now reverted the change which added a custom NeovideMinimize command and instead hooks into :suspend via UI commands.

We can now discuss about doing 'real suspend' further.

[MultisampledNight]

Do you want to rebase/merge main into this? Or should I do it?

[MultisampledNight]

I'll do it now then.
