Scenario: In Dia, create a UML class diagram, and name this class as say,
"TokenizedTable". Then add one operator "getType" with return value "const
string &". This operator should become a text "+getName(): const string"
inside the class diagram. Now export the diagram to SVG, and open that SVG
file again by Dia. The text "+getName(): const string " may be too long to
fit into the class diagram. 

The following is an exported SVG file:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg width="10cm" height="3cm" viewBox="2 1 10 3">
<rect style="fill: #ffffff" x="2.7" y="1.35" width="9.7" height="1.4"/>
