Created attachment 163694 [details]
Example file from Word

Attached document is a slightly simplified version of the Word2010 Title page template “Austin”.
It consists of several shapes whose size is set as a percentage value relative to the page size. Word conveniently shows this on its UI as absolute value too.
When imported to Writer these sizes are converted to an absolute value, with a slight rounding error:
The shape “Téglalap 34” (background with brownish gradient): 
Width 19.95 cm -> 20.43 cm (+0.48 cm)
Height 28.22 cm -> 28.70 cm (+0.48 cm)
The shape “Téglalap 35” (Blue textbox):
Width 7.77 cm -> 7.96 cm (+0.19 cm)
Height 8.91 cm >  9.06 cm (+ 0.15cm)
The shape “Téglalap 36” (tall white behind the blue and white text boxes)
Width 8.4 cm -> 8.56 cm (+0.16 cm)
Height 20.79 cm -> 21.10 cm (+0.31 cm)

Steps to reproduce:
    1. Open attached document

Actual results:
Shape sizes are slightly larger than in Word.

Expected results:
Shape sizes should be the same as in Word.
