Allow going below/above bar/shell with default-floating-position

[SnenxyTengoku]

Hi! I noticed that when using default-floating-position with a relative-to value, it will always be placed to fit within the shell/bar boundaries and won't allow the application to go above/below it by default unless it gets manually moved by the user. I understand this is a rather "niche" feature, at least in the niri sphere for how windows are managed here, but I can see some possible benefits to allowing it.

I was wondering if anyone figured out a workaround for this or if it would be possible to see if this could be an added option in the future?

My usecase for this is, uhhh... rather "Unique". Really, I would just like to see this work so that specific "windowed fullscreen" types of games (Windowkill, in this case _{(great game btw)}, of which runs perfectly fine but adds a blind spot on the bottom due to the game running in 1080p, but getting knocked below due to my bar) could work and integrate a lot better with niri, but I could see other possible use cases for this type of thing (like perhaps gpu-screen-recorder's UI allowing to be rendered "properly" instead of the fullscreen black background it gets by default and going over the whole display properly) if it were to be possible.

Bars can request exclusion zones for where window should not be

And for GSR, thats a them issue for being xwayland and not properly supporting wayland

Makes sense. Thanks.
