The tests show how recent Windows use per-monitor DPI to implement virtual display settings. This is only the case on the w11pro64_nv and w11pro64_amd virtual machines, and the other VMs only support per-monitor DPI scaling. Both these two scaling add up, and their effect is exposed by the GetDpiForMonitorInternal call, with the ANGULAR and RAW dpi flavors.
-- v2: user32/tests: Add tests with windows and monitor DPI scaling. user32/tests: Add more tests with display source DPI scaling. user32/tests: Add more tests for GetDpiForMonitorInternal. user32: Stub DisplayConfigSetDeviceInfo.
