    Fixes for recent versions of dia
    
    - Addressing the "image not found" issues when the PDF is
      generated with recent versions of dia.
      This doesn't happen yet on our server which is running Ubuntu 14.04
    
    - The problem happens with relative links to raster images
    
    - The problem can be solved by opening the image or svg file
      in Firefox or in the Gimp, copy it and then use "Paste Image"
      in Dia
    
    - A significant drawback is that the dia files are significantly
      bigger, and that the time to generate a PDF is substantially increased.
      This would probably be addressed by using Inkscape instead, but
      then we would need nice features of Dia, such as the use of a
      standard color palette (didn't find it in Inkscape), connectors, etc.
