+- sokol_app.h win32: Fix mouse locking behaviour in edge cases: an assert could
+  be triggered on Win32 when the mouse is currently locked and the window focus
+  is stolen via Ctrl-Shift-Esc or Ctrl-Alt-Del (basically: opening the task manager),
+  also even without the assert, the mouse might remain stucked in 'mouse lock mode'
+  while the task manager is open. The behaviour has been worked around by two changes:
+
+  - a return value `false` from GetCursorPos() will be handled instead of asserted
+  - a return value `false` from SetCursorPos() will be ignored
+  - trying to set lock the mouse while the application window isn't in the foreground
+    will be ignored
+  - the check whether a locked mouse must be unlocked now happens via polling
+    the current foreground window instead of WM_KILLFOCUS
+
+  See PR https://github.com/floooh/sokol/pull/1220 for details. Many thanks to
+  @Hisashimaru for bringing up the issue!
