The code is related to handling configuration files, I have a basic
configuration set, a hash called @output. And variants for on screen,
pdf, png export. I can avoid duplicates, of course, if I look at the
basic hash and at the special variants each time. But that is a little
bit more complicated and consumes more time, which is not really good.

All that is related to a graphical editor -- I have to clean up the code
a bit, it will become available on my page some time, then we can
discuss improvements. A tiny part related to cairo drawing is already
there:
