Suspicious attribute style:repeat="scale"

Hi all,

insert an Image-control. In its properties choose a picture and set the 
value for the item "Scale" to "Keep Ratio". Save the document.

Look into the file text. You will find the attribute 
'style:repeat="scale"' in the style:graphic-properties element of the 
associated style.

I do not find this attribute value in the ODF1.2 specification. For the 
attribute style:repeat only the values "stretch", "repeat" and 
"no-repeat" are possible.

Contentual such attribute value is useful. It covers the case that the 
picture is stretched to the size of the control while keeping the ratio 
of the picture. Such behavior would be useful too for background images 
and other fillings.

Kind regards
Regina
