Supporting other MC9 editions

The Windows backend is language independent. The Linux backend presses buttons by pixel position, and the positions in mc9/layout.py were measured on the Russian GUAP Edition of MC9 9.0.3 (window 1900x980, virtual screen 2000x1100). For another edition or UI language:

1. Open a circuit and take a window screenshot: c.shot("w.png", "window", trim=False).
2. In Layout, update the Linux-only block: the position of the Analysis menu title, the x of its items and the y of the first item, the limits-dialog Run button, the cursor dialog (field, Left, Right, Close), and the OK buttons of the two dynamic dialogs. Hover coordinates are easiest to read from a screenshot in any image viewer.
3. Set the Wine locale to your edition's (LANG in backends/linux_wine.py).
4. Run MC9_INTEGRATION=1 pytest tests/test_integration.py to confirm.

The tools/calib_*.py scripts show how label geometry and voltage-box placement were measured from screenshots; rerun them if your edition draws text differently.

Tip

If you only need the Windows backend's approach (keyboard accelerators + dialog classes), it can also drive Wine from inside the prefix - that is how the Windows driver is tested, and it avoids calibration entirely.
