Hi Hans, hi Steffen,

thanks for your comments on Python and that I don't have to recompile, 
that saves me a lot of time.

Yesterday evening, I figured out that I have to modify pydia-render.c 
and it works! =) Is there any reason why higher level methods like the 
rounded rectangle methods are not treated in that class? Otherwise I'd 
like to make a patch and commit it to the repository. Maybe it's better 
if someone takes a look at it before I do it ;-)

Another thing on the SVG renderer: You say that the Python renderer is 
far more complete and less buggy than the C version, but it seems that 
the generated code is rendered wrong in some viewers, for example in 
Firefox. So is there any reason why I should not use the attributes for 
rounding a rectangle and instead compose the rounded rectangles with 
other shapes?

I don't know what my renderer will look like once I'm finished, but 
maybe I commit it to GIT too. In any case I write an entry in our 
company's blog where I explain how to integrate Dia with Concordion.

Regards,

Max
