2 w3 H; u( l: g' O4 G1 i# Jdespite my initial negative answer, we finally went for the PNG
implementation - partly also because it will be needed for Resco News.

release, of course.

We stripped off anything that was not deemed necessary, so that the
footprint is minimal. (I would not believe that it can be made under 30K -

see these potential points:
