body: <p>how can i set the default font/size in UML designer?
  I changed it in the preferences sirius, but the diagram still uses the old default fonts (ubuntu 9) which is just to tiny on my big screen.
  i have to change the font manually to 12 for each class/component and to 10 for each operation, property, link etc.</p>
