Daniel d'Andrada has proposed merging lp:~dandrader/qtubuntu/resizeToolTip into lp:qtubuntu.

Commit message:
Resize menus and toolips when told to do so

Requested reviews:
  Ubuntu Phablet Team (phablet-team)

For more details, see:
https://code.launchpad.net/~dandrader/qtubuntu/resizeToolTip/+merge/313798

Fixes the following bug that you can see when running the childWindows branches + https://code.launchpad.net/~alan-griffiths/miral/fix-1652109/+merge/313782

1 - launch Kate
2 - Open some big text file (at least hundreds of lines long)
3 - scroll to the very top
4 - shorten the Kate window so that it doesn't not show many lines at once
5 - press and hold the down arrow on the scroll bar
6 - see the tooltip displaying some line numbers

expected outcome:
tooltip gets wider once it starts diplaying numbers bigger than 99

actual outcome:
numbers get squeezed once they get past 99
