[PATCH] SVGAbstractTranscoder doesn't recognize dimension changes on SVG-ROOT

[Simon Mieth]

Hi all,

the currrent Transcoder doesn't recognize changes of the dimension on
the SVG-Root element by a script (invoked by -onload). Changes on other
elements are generated fine. This problem was described by other user on
the user-list [1].

The patch is quite simple, it invoke the script before the dimension
(height and width) are read from the document. 
The current implementation invokes the script after the dimension are
set to the result image.

Best Regrads,
Simon
