Fixed-size\nsatellites resolve their placement synchronously during construction so\nthe window is created at its target position; sized-to-content\nsatellites position from ApplyContentSize after the first frame. Both\npaths align the window frame, rather than the window rectangle, with the\npositioner\u0027s origin.\n- Add HostWindow::CreateSatelliteWindow\n- Propagate parent movement on `WM_WINDOWPOSCHANGED` to satellites in\norder to move them with their parent\n- Reject reparenting that would make a satellite its own ancestor\n- Implement SatelliteWindowControllerWin32 and its FFI bindings\n- Add satellite windows to the example application\n\n## How to test?\nRun the multiple windows example application and play with satellites\nthere :tada:\n\n## Pre-launch Checklist\n\n- [x] I read the
