Can't move window to next display past a fullscreen window about rectangle HOT 2 CLOSED

I'm not opposed to adding this in but it might take a while for me to get around to it.

If anyone wants to submit a PR for it, it shouldn't be much work. I didn't look to see how Spectacle might have done this, but you should be able to cycle through the windows on a target screen and determine if a window is the same size as the screen (see https://stackoverflow.com/questions/23844148/how-do-find-out-if-there-is-a-full-screen-app-running-on-a-specific-nsscreen). A quick search on Spectacle's code doesn't show this specific way being done there.

I took a look at this one, and here's what I found.

Spectacle does not do this (and neither does Magnet FWIW). At first, I thought it did, but it turned out that Spectacle has a bug where it cycled through displays backwards - my fullscreen app in the middle of three displays appeared to be skipped but it just cycled through displays the wrong way.

With that in mind, I don't have plans to investigate this further. If someone else wants to give it a go, I don't see a reason to turn down a PR with it. I spent a while digging in Spectacle's code when I thought that it did it, and did find something worth taking a look at if someone were to implement this. It's a way to see if a window is full screen using the accessibility API, as follows:

- (BOOL)isFullScreen
{
  ZKAccessibilityElement *fullScreenButtonElement = [self elementWithAttribute:kAXFullScreenButtonAttribute];

  return [[fullScreenButtonElement stringValueOfAttribute:kAXSubroleAttribute] isEqualToString:(__bridge NSString *)kAXZoomButtonSubrole];
}

Here's the commit where I found it

This might be a better way to determine if a window is fullscreened than comparing the size of the window to the screen (I don't know for sure, though).

Since I'm not going to implement this, I'm closing the issue. Although a PR is welcome if anyone else wants to do it.
