Subject: MenuStatusCallback when menu was closed did not return location of pointer relative... 
X-Git-Url: http://git.mutantstargoat.com/user/nuclear/?a=commitdiff_plain;h=29ce77740209818d54bdea174d193307314f4084;p=freeglut

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.
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)
