When WindowFromPoint is called with a point inside the transparent region of the top-level window, the top-level window is returned instead of the expected window beneath it. I found that this problem was previously addressed in the patch [https://gitlab.winehq.org/wine/wine-staging/-/blob/master/patches/user32-Mou...]. I adapted that patch for the current version and added a test. -- v3: Add support for a layered window region. (v3) https://gitlab.winehq.org/wine/wine/-/merge_requests/11030
