Strange, as on tinderbox complains. Anyway, the problem is not specific
to Writer, it affects Calc and Impress as well, see commit
e16b01a9e4e111b1267c4eec1f5d168e5c2b8e53 (it's the shared drawingML
export code).

Each time I write such an assertion, I add a comment about what was the
old/wrong value, so in case you get 1999 instead of 2000, you have a
chance to judge if the old rounding error is back or in fact the 1999 vs
2000 is not a big difference in this case. In this case, it says "the
image become invisible", so hopefully you can easily just manually load
and save the document and verify if on your machine the image becomes
invisible in Word or not. :-)

Thanks,

Miklos
