sw export test failures

Hi,

on very recent master (9aad656156fbf76288e8a281760e60f1eccc6622),
on VS 2013 the xmlexport tests are failing here [1]:

        // This is 17667 in the original document, was 504666 (so the image
        // become invisible), now is around 19072.
        CPPUNIT_ASSERT(getXPath(pXmlDoc, "//a:srcRect", "l").toInt32() 
< 20000);

looking into it, reveals that the XPATH in question is:

   <a:srcRect l="23842" t="0" r="23842" b="0" />


the whole word/document.xml is [2] and the stack trace is [3].
It looks like this test was added recently, in this commit: 4cdce63d.

On VS2013 i was able to build LO with all tests before. When i increase
the value to 24000 to pass this specific tests, then the next test that is
failing is: testExportImageProperties::Import_Export [4], that sounds
familiar:

'hspace' of '/html/body/p/a/font/img' incorrect value
