[Geany] geany plugin for pyflakes - formatting text in editor

[Filip Gruszczyński]

Hi!

I am writing a small plugin that will integrate pyflakes into Geany. I
have managed to spawn pyflakes process and retrieve information from
pyflakes and now I have to use it to decorate some text in code or
maybe add some icons to the line numbers bar on the left. I took a
look at GeanyDocument and GeanyEditor, but I don't see any functions
that could be used for that. Could you advise me a little, what should
I use?
