Screen coordinates for the main Squeak window/host windows

Hi John, Hi Vanessa, Hi HostWindowPlugin folks,

I've managed to compute window rectangles for WindowEventMetricChange events correctly on macOS/Cocoa. But I'm not sure whether the origin of a window includes its menu bar or not.

So should the origin of the Squeak Window be reported as the position relative to the top left of the Mac's main display of...

- the origin of the host window containing the Squeak window ?

- the origin of the Squeak display (which is menuBarHeight screen coordinates further down than the window origin) ?

Similarly should the HostWindowPlugin report window origins and sizes for the actual host window, or form the content of the window, offsetting downwards by the menu bar height?

Maybe check Chrome's "Multi-Screen Window Placement API" docs?

Another idea would be to check what X11 window managers do - I think they do respect app's placement wishes.

No time to get into this atm unfortunately.
