overlappingControls.ods: overlapping checked and unchecked box at same position
The problem is that LO waffles on which overlapping control to show at the top.
Sometimes it paints the checked one, and sometimes it paints the unchecked one.
Obviously it is very bad document design by the user to overlap two controls,
so in a certain sense this "problem" is a "feature" that hints to the user that
there is a document design problem that needs to be fixed.
Steps to reproduce:
1. open overlappingControls.ods (I see a checked box)
2. click-on/move-to a different cell (I now see an unchecked box)
3. use the scrollbar to scroll down (I now see a checked box again)
I bibisected this to a range of unbuild-able LO 5.0 timer commits on

However, I think that probably just exposed an existing problem.
Notable commits related to this seem to be:
-commit cfa994ccbd6ee (Mon Jun 24 20:17:43 2013)
-commit 1856186951a70 (Sat Apr 14 12:46:04 2012)
but neither of those two seemed to change the paint order...
