Code review comment for lp:~dandrader/unity8/childWindows

tested with tiled and kate (qt5 apps), brief test with tiled and kate, the child windows positioning works, if i move the parrent window, the child windows moves according to parrent's x/y. in the app switcher (alt tab) i see both the parrent and the child window. the menus open in a separate window with a wrong size and position and it usually ends up freezing unity8 when i try to close the menu or or parent. tooltips same as with menus. short video here https://vid.me/aCWQ
