    tdf#96892 higher precision pdf fixed ints
    
    reverts
    
    commit 5f6065f980756fdb81c7018bedbb7f54e2b8214a
    Date:   Thu Mar 3 20:44:47 2016 +0000
    
        coverity#1355126 Logically dead code
    
        maybe we should be using more precision, but we haven't
        been in the past
    
    and...
    
    commit cd5cc12d4330d68d0a233a82eda30e983ce202a4
    Date:   Thu Mar 3 20:42:52 2016 +0000
    
        nLog10Divisor is 1
    
    and then fix the original appendFixedInt bug wrt higher precision settings
    
    and then bump those settings from 1 decimal place to 3 and adjust our
    pdf export test for the new precision
