past with some of the xml layout unit tests in sw on OSX - making rect
calculation rounding errors spring to mind causing the unit test to
fail. As I only reported these at the time, and not involved in fixing
them, I can't say I understand the details.

I also wonder whether the horrible black or white bands and other
display detritus we see on OSX in fullscreen would be affected by
changes in this area (for the better hopefully)
