Removing the 0.8 scale factor appears to be good to me (I've edited the extension code myself), because picture appeared to be exactly 0.8 times its original size. BTW, since the scaling is so weird across different versions, I'd recommend writing the function GetSVGScaleFactor() to get the ratio (i.e. 0.8 or 1.0). Anyway, the logic in the odt above does not look good. I have no reason to believe that that 1.25 multiplies with 0.8.
