// MonitorPickerDialog — visual monitor map shown when the user requests a
// new window on a multi-monitor system. The dialog draws each connected
// QScreen as a scaled rectangle (preserving the virtual-desktop layout) and
// lets the user click the monitor where the new window should appear.
//
// Use MonitorPickerDialog::pick() instead of constructing directly — it
// short-circuits the dialog when only one monitor is connected.
