[zbynekstara]

Description

According to the source code, dia.Element.size() has the following three signatures:

• getter (no arguments) = return this.get('size')
• setter (two arguments, first argument is an object) = read width and height from first argument (if not present, get the missing value from the current size attribute), pass width, height, and second argument to this.resize as width, height, opt
• setter (three arguments) = return this.resize(width, height, opt)
