Window mode issues about unciv

Add: Multimonitor - Window doesn't save which Monitor it was on.

I had a working solution once, but it relied on ugly hacks under the hood as the used libraries already bungle what an app that wishes to 100% restore its state needs - down to but not limited to the GLFW layer. That's below LwJgl3, which is below Gdx. Outdated branch still around.

On second look - this is mostly already documented in source, except for point 1. OK, maybe point 3 detail "imprecise" isn't explained either in that comment - but I seem to vaguely remember we already had an issue where Windows was set to scale by 150% or worse and in that issue we learned that the underlying libraries - below Gdx - behave inconsistently when that is the case (some reported coordinates/dimensions which should be in pixels are scaled by that factor instead), which likely explains that as well. ...#9886 was it. So is your "fails to fully fill up" or "imprecise" maybe proportional to your windows scaling setting?

On third look - #1 is by design, probably. You can't drag any window big enough so that after removing borders it will still fill the screen entirely - obviously. What you get is the size of the inside of the window before switching to borderless. Just guessing without actually testing - I'm that lazy. But I bet that fits.
