SVG: scaling if no width/height is given

Hi Christina,

I have seen you patch at Gerrit now.

I think, that SvgAspectRatio::createLinearMapping is the wrong place to 
constrain the scaling because this method is used in svgimagenode.cxx 
and svgstyleattributes.cxx too. I think, that the decision whether to 
keep aspect ratio or not, should be made in the node itself. Have you 
tried to set the default settings explicitly in the constructor of 

Kind regards
