MenuStatusCallback when menu was closed did not return location of pointer relative to child window's top-left, it only worked for top level windows.

Browse Source 
To make this work, fghPlatformGetCursorPos now can return cursor pos relative to top-left of a specified window's client area (this is untested on X11)
