I'd like to second Simon's comments, very unselfish and good work Andreas.

I am pleased that you undertake this kind of cleanup work in the
layout engine. It is very useful that you try to make this piece of
code more accessible.

Checking closer, the code was still way too messy for my taste, so I went further --and further... Quite far, actually, so a bit of explanation needed in case someone goes looking for code that I removed.

It seemed like an experiment from Luca, that likely should have been kept in a branch instead of being committed to the trunk in an incomplete state. All it did here was confuse people, in a class which is quite heavily used.
