Issue Description

EXCEL 2007, in a merged cell ( example col 2 to col 5), I put 5 pictures with size 76 * 76px, and call Resize() to make the picture is displayed as original size. but from the 3rd picture, it has wrong width, becaue it is cross the col2 and col3, the dx2 of anchor looks not right. check the width in Excel app, the original size is right, but the scaleY is greater than 100%.

the above issue is occured on V2.5.6.

on 2.7.1 all prctures are removed after Resized() called.
