From: Zhiyi Zhang zzhang@codeweavers.com
To test that GetThemePartSize() should always report theme part size in system DPI if the theme handle is open without a valid window handle. Previous tests succeeded because the current DPI happens to be 96.
Tested manually on Windows 10 for 96, 120, 144, 168, 192 and 216 DPI.
