Fwd: [calligra] libs/kotext/styles: Use QTextLength for paragraph margins

I have done some testing and I found some stuff that looks now not as good as 
before. I'm not 100% sure where the problem is located bug one thing I noticed 
quite havily is that the line height in presentations seems to be wrong now. 
I have searched for the commit that is to blame and 

8b11085ba0246c608ecc1f6a81165b8af114017e

is still ok while with 

eff8fc64237e80dc75c920704d05c8c7aca3fb50

the distance is smaller. I have uploaded the files to 
http://www.zagge.de/anchor/length/

in after there are the images created with eff8fc
in before there are the images created with  8b1108

Also indention is a bit strange now. For second rows

I have uploaded 2 files for now showing the problem and can upload many more if 
quite a lot of files look different now.

Would be good if you could fix that.
