pictures.add: Excel is slightly changing the dimensions if the original chart changes

[fzumstein]

Even if you reset the chart, it will be slightly distorted, e.g. 97%/103%

might be fixable with this:

sheet.shapes[0].api.ScaleHeight(1, True)
sheet.shapes[0].api.ScaleWidth(1, True)

sheet.shapes[0].api.scale_height(scale=k.scale_from_top_left, relative_to_original_size=True, factor=1)
sheet.shapes[0].api.scale_width(scale=k.scale_from_top_left, relative_to_original_size=True, factor=1)
