improvement to juce_areThereAnyAlwaysOnTopWindows


This is the current code for the function:

bool juce_areThereAnyAlwaysOnTopWindows()
    NSArray* windows = [NSApp windows];

    for (unsigned int i = 0; i < [windows count]; ++i)
        const NSInteger level = [((NSWindow*) [windows objectAtIndex: i]) level];

        if (level == NSFloatingWindowLevel
             || level == NSStatusWindowLevel
             || level == NSModalPanelWindowLevel)
            return true;

    return false;

When I open an AlertWindow inside my plug-in in Reaper, it falls behind the current plug-in window, meaning that the function above returns false while it should have returned true.

Digging a little further, I have found that the "level" value for the plug-in windows in Reaper is "1", which does not match any of the values tested in the if (and, as long as I have been able to find, does not match any of the "official" values for the level property either)

Anyway, since the level property is meant to represent the z-axis stacking of windows, what do you think about replacing the condition in the if above with a much simpler "level > NSNormalWindowLevel"

        if (level > NSNormalWindowLevel)
            return true;

After all, from the JUCE point of view, any window that's above the "normal" level should be considered always on top
