Hmmm. If I could find informations about the "standard pycairo way" I
would implement this ASAP. The documentation about this standard and
(for me) the CTM was poor so it caused some headache to get my chart
engine work properly.
Where could I find more informations about this? I would be happy if the
long awaited documentation about the cairo graphic model would be
available online ;-)

No doubt - I would be happy to use my charts i.e. in my TeX-files
without the need to convert png via pdflatex.
