  Log:
  Quoting Rob Oxspring :
  
  I was using the image task to create thumbnails and couldn't figure out
  how to keep proportions of an image but keep it within a fixed size.
  My solution was to change the keepproportions attribute to be a little cleverer.
  The keepproportions attribute is no more and has been replaced by the proportions
  attribute, which has been added with the following features:
  
  proportions="ignore" - treat the dimensions independently (==keepproportions="false" and
is default)
  proportions="width" - keep proportions based on the width (==keepproportions="true")
  proportions="height" - keep proportions based on the height
  proportions="fit" - keep proportions and fit in the supplied dimensions
  proportions="cover" - keep proportions and cover the supplied dimensions
