winex11.drv: Retry last ClipCursor when grab is released. As we ignore these NotifyGrab / NotifyUngrab w.r.t focus decisions, some applications are unaware of mouse grabs being lost and sometimes cursor clipping is lost. We have to keep the last clip rectangle and restore it when grab is released. This has been squashed with the foreground window check from Zhiyi Zhang <zzhang@codeweavers.com> to fix an issue that happens when switching from a fullscreen window - because there's some additional focus events involved - but in general, if the window that is getting focus cannot be activated: When FocusIn/NotifyWhileGrabbed is received, SetForegroundWindow is not called if the window cannot be activated. When the FocusIn/NotifyUngrab event arrives for the same window, we have to check the foreground window before restoring cursor clipping rectangle. For reference, the event sequence when pressing Alt-Tab - for WMs that grab the keyboard - is the following: 1. FocusOut/NotifyGrab, when WM grabs the keyboard. 2. FocusOut/NotifyWhileGrabbed, while WM switches windows, this calls SetForegroundWindow(GetDesktopWindow()). The event sequence for normal windows ends here, but for fullscreen windows, there may be these additional events: 3. FocusIn/NotifyWhileGrabbed, which may not change Wine foreground window if it cannot be activated. 4. FocusIn/NotifyUnGrab, when WM releases the keyboard while switching windows, this is ignored but it should not retry to grab the cursor, because window is not foreground. 5. FocusOut/NotifyNormal, when WM finishes switching the windows.
