Can't turn overlays into QWidgets on Mac #1

Mac OS seems to have an issue with changing child widgets in response to dragEnter/dragLeave events (it emits a couple of them immediately, causing the code to change the child widget again... and repeat).

This makes it difficult to have a modern and responsive UI... or to use VisTrails?'s configuration widgets in the overlays.

Fixed by a5156584e3, thanks to qt-project.org

No, as of ccf942a9a5, there is still an issue. Replacing a widget by another (with WA_TransparentForMouseEvents set) during the drag provokes a seg fault (on Mac OS only).

e6f67186b0 works around this issue by making sure that ALL overlays have WA_TransparentForMouseEvents set for the duration of the drag. The code is not pretty but I haven't found a more elegant solution yet...
